How to Improve Your Credit Score Before a Loan (2026 Plan)

Person reviewing credit reports and a calendar while preparing to apply for a loan or mortgage

Last reviewed: October 1, 2026

Short answer: To improve your credit score before applying for a loan or mortgage, work in this order. Pull your free reports from all three bureaus and dispute real errors. Pay revolving balances down before each card's statement closing date so a lower balance is reported. Bring any late account current and automate every payment. Stop applying for new credit. Keep old cards open. Then let the changes report before the lender pulls your file.

Some of this works quickly. A lower reported card balance can show up at the next monthly update, and a dispute is normally investigated within about 30 days. Other things only heal with time: accurate late payments and collections can stay on a US credit report for seven years. Start 90 days ahead for a personal or auto loan and six to twelve months ahead for a mortgage if you can.

This guide is a time-boxed action plan, not a theory lesson. It covers what to do in the first 30, 60 and 90 days and over six to twelve months, and which popular "tricks" backfire. It draws on the Consumer Financial Protection Bureau (CFPB), the Federal Trade Commission (FTC), myFICO, the credit bureaus' education pages, Fannie Mae, Freddie Mac, the UK Information Commissioner's Office (ICO) and the Financial Consumer Agency of Canada (FCAC).

How much your score matters for approval and price

Your credit score affects two things: whether you are approved and what you pay. Freddie Mac's consumer site puts it simply: stronger credit shows lenders you manage money responsibly, and higher scores open the door to better loan terms and lower interest rates.

Most lenders price in tiers. A score a few points below a tier boundary can mean a higher rate, a larger required down payment or a decline, while a score a few points above it is treated the same as a much higher one. So you may not need a dramatic jump, only enough to reach the next tier.

Illustrative example: what one pricing tier can cost

The figures below are fictional and for illustration only. They are not real or current rates. They show the arithmetic when the same loan is priced in two different tiers.

Fictional loan	Rate tier (illustrative)	Monthly payment	Total interest	Difference
Personal loan, $25,000 over 60 months	Lower tier: 14.0% APR	$581.71	$9,902.60	$62.75 a month; $3,765.00 over the loan
Personal loan, $25,000 over 60 months	Better tier: 9.0% APR	$518.96	$6,137.60	$62.75 a month; $3,765.00 over the loan
Mortgage, $300,000 over 30 years, fixed	Lower tier: 6.5%	$1,896.20	$382,632.00	$97.55 a month; $35,118.00 over the full term
Mortgage, $300,000 over 30 years, fixed	Better tier: 6.0%	$1,798.65	$347,514.00	$97.55 a month; $35,118.00 over the full term

Payments are principal and interest only, rounded to the cent, with total interest worked out from the rounded payment. Taxes, insurance and fees are left out. On a long loan, even half a percentage point adds up to a large sum.

If you want the background on how scores are built, read our explainer on what a credit score is and how it is calculated.

Which score your lender uses and when to start

There is no single credit score. The score in your banking app is probably not the exact score your lender will pull, so use it as a direction indicator, not a guarantee. What matters is fixing the underlying report data, which every scoring model reads.

myFICO, the consumer arm of the company behind FICO Scores, explains that different versions are used for different products.

Loan type	Scores commonly used (per myFICO, Experian and Fannie Mae)	What it means for you
Mortgage	Older "classic" FICO versions: FICO Score 2 (Experian), FICO Score 4 (TransUnion) and FICO Score 5 (Equifax). Fannie Mae's Selling Guide also lists VantageScore 4.0 as eligible for approved lenders.	The lender usually pulls all three bureaus. Experian says lenders may use the middle score and, on a joint application, typically the lower of the two middle scores.
Auto loan	FICO Auto Scores, industry versions that run from 250 to 900, or a base score, depending on the lender.	Past auto loan behavior can weigh more.
Credit card	FICO Bankcard Scores or base FICO Score 8 or 9.	Card behavior weighs more.
Personal loan	Often a base score such as FICO Score 8, which myFICO calls the version most widely used by lenders.	Ask the lender which bureau and score it uses.

Two points follow. For a mortgage, all three reports matter, and some benefits of newer models, such as ignoring paid collections, do not apply to the older versions. And you can ask a lender which bureau and score it uses: the CFPB notes that a lender cannot pull your report if you are simply asking about rates.

When to start

Start as early as you can, because the slow items set the pace. myFICO says people who are rebuilding may begin to notice small changes within three to six months, while recovery from serious problems takes longer. As a working rule, give yourself at least 90 days before a personal or auto loan and six to twelve months before a mortgage.

Step 1: Pull all three credit reports

Begin by getting your reports from Equifax, Experian and TransUnion, because you cannot fix what you have not seen. The FTC says the three nationwide bureaus have permanently extended a program that lets you check your report from each one once a week for free. The only authorized source is AnnualCreditReport.com.

Checking your own report is a soft inquiry and, the CFPB confirms, does not affect your scores.

What to check

The CFPB groups common errors into identity errors, incorrect account status and data errors. Go through each report and mark anything on this list:

Identity details: wrong name, address or phone number, or accounts that belong to someone with a similar name.
Accounts you do not recognize, which can be a sign of identity theft.
Status errors: closed accounts shown as open, accounts wrongly shown as late or delinquent, or being listed as the owner of an account where you are only an authorized user.
Dates: wrong date of last payment, date opened or date of first delinquency.
Duplicates: the same debt listed more than once, perhaps under different names.
Balances and limits: an incorrect current balance or an incorrect credit limit. A limit reported too low makes your utilization look worse than it is.

Compare the three reports with each other. The FTC points out that they may contain different data, because not every creditor reports to every bureau. Dispute an error at each bureau where it appears.

Step 2: Dispute real errors

Dispute anything that is inaccurate or incomplete, and only that. Disputing is free, you can do it yourself, and the bureau generally has 30 days to investigate, according to the FTC.

The process

Dispute with the bureau that shows the error. The CFPB advises including your full name, address and phone number, the report confirmation number if you have one, the account number, an explanation of why the item is wrong, a copy of the report section with the error highlighted, and copies of supporting documents.
Dispute with the furnisher too. The furnisher is the company that supplied the information, such as a bank or card issuer. The CFPB says to contact both the bureau and the furnisher. A furnisher that receives a written dispute must investigate and respond, generally within 30 days.
Wait for the written result. The FTC explains that the bureau must forward your evidence to the furnisher and give you the results in writing. A furnisher that finds its information was wrong must notify all three bureaus.
If you disagree with the outcome, you can ask for a statement of the dispute to be added to your file, and you can submit a complaint to the CFPB.

Keep copies of everything, and mail disputes with proof of delivery.

Timing before an application

Send disputes at least 45 to 60 days before you plan to apply. That allows for the investigation and for the correction to appear. An account marked as in dispute can slow mortgage underwriting, which is another reason to do this early.

What counts as an error, and what does not

A payment shown as late that you made on time is an error. So is a collection for a debt that is not yours. A payment that really was late is not an error, even if there was a good reason for it.

The FTC is blunt on this: as long as the information is correct, a bureau can report most negative information for seven years, and bankruptcy for ten. A bureau can also stop investigating a dispute it considers frivolous, although it must tell you. The CFPB adds that this notice must come within five business days of the decision.

Disputing accurate information wastes the weeks you have: once verified, the item stays. The FTC also lists being told to dispute accurate information as a sign of a credit repair scam.

Step 3: Lower your credit utilization

Paying down credit card balances is usually the fastest legitimate way to raise a score, because utilization is calculated from the most recently reported balances. Experian explains that scoring uses only the latest reported numbers, not past high balances.

Utilization is your revolving balances divided by your revolving limits. The CFPB says experts advise keeping it at no more than 30 percent of your total limit. myFICO suggests below 30 percent and ideally under 10 percent. Scoring looks at the overall ratio and at each card's own ratio.

Pay before the statement closing date, not just the due date

Card issuers generally report your balance to the bureaus once a month, around the end of the billing cycle, and the figure is often the balance on the day your statement closes. The due date comes about three weeks later, so someone who pays in full on the due date can still show high utilization.

Find each card's statement closing date and make a payment a few days before it, so a low balance is reported. Then pay any remaining statement balance by the due date. The CFPB says you do not need to carry a balance to have a good score.

Spread balances sensibly

If one card is nearly maxed out while others sit empty, pay the maxed card down first. Do not move everything onto a single card just to tidy up: the CFPB warns that consolidating balances onto one card can hurt your score if it pushes that card's usage up relative to its limit.

Illustrative example: utilization before and after

This example is fictional. The borrower has $3,600 of savings available to reduce card debt two months before applying.

Card (fictional)	Limit	Balance before	Utilization before	Balance after	Utilization after
Card A	$5,000	$3,900	78%	$600	12%
Card B	$3,000	$600	20%	$300	10%
Card C	$2,000	$0	0%	$0	0%
Total	$10,000	$4,500	45%	$900	9%

The borrower pays $3,300 toward Card A and $300 toward Card B, a total of $3,600, before the statements close. Overall utilization falls from 45 percent to 9 percent, and no single card is above 12 percent. How many points that is worth depends on the rest of the file.

Asking for a credit limit increase

A higher limit lowers utilization without paying anything down, but it has a catch. Equifax says a request for a limit increase will often result in a hard inquiry, although not always, and that it depends on the creditor's policy.

Ask the issuer first whether the request uses a hard or a soft pull. If it is a hard pull and you are within a few months of applying, it is usually better to skip it.

If you cannot pay the balances down

Moving large balances to an installment loan or a promotional-rate card also adds a new account and a hard inquiry, so do it well ahead of a major application. Our guides to debt consolidation options and costs and balance transfer credit cards explain the trade-offs.

Step 4: Fix and protect your payment history

Payment history is the largest factor in a FICO Score, at about 35 percent, so the single most valuable habit before a loan application is zero new late payments.

Catch up on anything past due

If an account is behind, bring it current now. myFICO notes that the longer you pay on time after being late, the more your score should recover, and that older problems count for less than recent ones.

Getting current does not erase the late mark, which can remain for up to seven years, but the account stops reporting new damage.

If you cannot afford to catch up, call the creditor before the next due date and ask about hardship arrangements. The FTC suggests finding a reputable nonprofit credit counselor through credit unions, universities or military programs.

Goodwill requests: possible, not promised

A goodwill letter asks a creditor to remove an accurate late payment as a courtesy. Experian describes it as most useful for a single late payment on an account that is now current, with a clean record before and after and a reasonable explanation.

Keep expectations low. The creditor has no duty to agree, and Experian notes that many say they must report payment history accurately and will not adjust accurate information. It will not fix a pattern of late payments, a charge-off or a collection.

Automate the minimums

Both the CFPB and myFICO recommend automatic payments or reminders. Set autopay for at least the minimum payment on every account, including the cards you rarely use, then make your larger manual payments on top.

Also update your address with every creditor, and look for small forgotten bills, since unpaid bills can be sent to collections.

Step 5: Deal with collections and charge-offs

Collections and charge-offs are serious negatives, and paying them does not automatically remove them. Experian says a collection stays for seven years from the date the original debt first became delinquent, paid or not. How much paying helps depends on the scoring model.

First, validate the debt

Before you pay a collector you do not recognize, confirm the debt is real, yours and for the right amount. The FTC explains that a collector must give you validation information at first contact or within five days. It includes the creditor's name, the itemized amount and how to dispute.

You have 30 days from receiving that information to dispute the debt in writing. Once the collector receives your dispute, it must stop collecting until it sends you written verification.

Check the date as well. The FTC warns that after the statute of limitations runs out a debt becomes "time-barred", and that in some states a payment, or even a written acknowledgment, restarts the clock so the collector can sue for the full amount. If the debt is old, get advice before you pay or sign anything.

How scoring models treat paid collections

According to Experian, FICO Score 9, FICO Score 10 and 10T, and VantageScore 3.0 and 4.0 disregard paid collections, while older models such as FICO Score 8 still count them.

The classic FICO versions still common in mortgage lending are older than FICO Score 8. So paying a collection may lift some of your scores and leave your mortgage scores almost unchanged. Paying can still be worth it, since some lenders want open collections settled. Ask your loan officer before paying an old collection mid-application.

"Pay for delete": handle with caution

"Pay for delete" means offering to pay a collector in exchange for the account being removed from your reports. Collectors do not have to agree, so do not build a plan around it. If one does agree to change its reporting, get that in writing before you pay.

Medical debt reporting

Medical collections are treated more leniently than other collections under voluntary changes made by the three bureaus. As confirmed by the CFPB and Equifax:

Paid medical collection debt has not been included on US consumer credit reports since July 1, 2022.
Unpaid medical collections do not appear until at least one year has passed, up from six months.
Medical collections with an initial balance under $500 were removed in April 2023.

If a medical collection that fits one of these categories is still on your report, dispute it. A medical bill paid with a credit card is ordinary card debt. A wider federal rule on medical debt reporting was finalized in early 2025 but later set aside in court, so the bureaus' voluntary policies are what applies.

Charge-offs

A charge-off means the original creditor has written the debt off as a loss. You still owe it, and it can be sold to a collector. Like other negative items, it can stay on your report for seven years. Paying it updates the status, which lenders prefer to see, but the history stays. If the charge-off and a collection account for the same debt both show a balance, dispute the duplicate.

Step 6: Avoid new credit and hard inquiries

In the months before a major application, do not apply for anything you do not need. A new account adds a hard inquiry and lowers the average age of your accounts.

The effect of one inquiry is small. myFICO says one additional inquiry takes less than five points off most people's FICO Scores, that inquiries stay on the report for two years, and that FICO Scores only consider those from the last 12 months.

New credit cards, store cards offered at the checkout and some financing plans trigger hard inquiries. Checking your own credit and prescreened offers are soft inquiries and do not affect scores.

The rate-shopping window

Shopping around for the same type of loan is protected, so do not let fear of inquiries stop you from comparing offers.

Mortgages: the CFPB says multiple credit checks from mortgage lenders within a 45-day window are recorded as a single inquiry.
Auto loans: the CFPB says inquiries made within 14 to 45 days of each other generally count as one, depending on the scoring model.
FICO's rules: myFICO explains that older FICO versions use a 14-day window and newer versions a 45-day window, and that FICO Scores ignore mortgage, auto and student loan inquiries made in the 30 days before scoring.

The safe approach is to do all your rate shopping for one loan inside 14 days. A mortgage inquiry and an auto loan inquiry count separately, and credit card applications are not grouped this way.

Step 7: Keep old accounts open; authorized users

Do not close credit cards before applying for a loan. myFICO says closing unused cards as a short-term strategy can hurt your score by reducing your available credit, which raises utilization. Keeping older accounts open also supports the length of your credit history.

If a card has no annual fee, keep it open and put one small recurring charge on it with autopay, so the issuer does not close it for inactivity. If a card has a fee you no longer want to pay, time any closure for after your loan has funded.

Authorized user status and its limits

Being added as an authorized user on someone else's well-managed card can help, mostly for people with thin files. Experian explains that the account's limit and payment history can appear on your report, which may improve payment history, lower utilization and add account age.

The limits are real:

It works both ways. If the primary cardholder pays late or runs a high balance, it can hurt you. Experian says it does not include negative information on authorized users' reports, but other bureaus may.
Not every issuer reports authorized users to all three bureaus. Ask before relying on it.
Only do this with someone you know and trust. Do not pay a stranger to add you to their card, a tactic sold by some credit repair schemes.

Step 8: Build a thin credit file

If you have little or no credit history, the goal is to add positive data that actually gets reported, and to do it early, because new accounts need months to help.

Secured credit card

The CFPB describes a secured card this way: you put down a cash deposit, for example $500, and can then spend up to that amount. Confirm first that the issuer reports to all three bureaus. See our guide to how secured credit cards work.

Credit-builder loan

A credit-builder loan, usually from a bank or credit union, lets you build credit and savings together. The CFPB says these loans typically run 6 to 24 months and that the money is held as savings instead of being handed to you up front. A missed payment hurts as it would on any loan.

Rent and utility reporting

Rent is not usually reported automatically. Experian notes that only a small share of tenants' rent payments reach the bureaus. Rent reporting services, used by a landlord or signed up for by a tenant, can add those payments. Services differ in which bureaus they report to and whether they charge a fee.

The benefit depends on the scoring model. myFICO says FICO Score 9 factors in rental history when it is reported, and Experian says the newest FICO versions and VantageScore can use it. The older scores used for many mortgages may not. Late or unpaid rent can also be reported or sent to collections.

What does not build credit

The CFPB lists products that generally do not help because the payments are not reported to the nationwide bureaus: debit cards, prepaid cards, payday loans and "buy here, pay here" auto loans.

Timeline: what can change in 30, 60 and 90 days and 6 to 12 months

Quick wins come from correcting data and lowering reported balances. Slow wins come from time passing with clean payments. The table shows what is realistic in each window.

Window	What to do	What can realistically change	What will not change yet
Days 1 to 30	Pull reports. File disputes. Pay cards down before statement dates. Bring accounts current. Set up autopay. Stop new applications.	Lower utilization can be reported at the next monthly update. Past-due accounts stop adding new late marks.	Accurate late payments and collections remain. Dispute results are usually still pending.
Days 31 to 60	Review dispute results. Keep paying before statement dates. Send a goodwill request if it fits. Validate any collection.	Corrections from successful disputes appear. A second month of low balances and on-time payments is reported.	Inquiries from the past year still count. New accounts are still young.
Days 61 to 90	Hold steady. Re-check reports. Prequalify with soft pulls where offered.	Three clean months since any catch-up. Data is stable enough to apply for a personal or auto loan.	Serious negatives still weigh on the score, though a little less each month.
6 to 12 months	Keep utilization low. Let secured cards or credit-builder loans age. Pay down debt.	Thin files gain a real track record. Older inquiries stop counting in FICO Scores after 12 months. Recent late payments carry less weight as they age.	Accurate negatives stay for up to seven years, and bankruptcy for up to ten.

Results depend on your starting file. Be wary of anyone who guarantees a specific gain by a specific date.

Mortgage-specific preparation

A mortgage is the application where preparation pays most, because the loan is large and the lender checks your file more than once.

Debt-to-income ratio counts alongside the score

The CFPB defines your debt-to-income ratio (DTI) as all your monthly debt payments divided by your gross monthly income. It adds that different loan products and lenders have different DTI limits.

Here is a fictional illustration. A borrower earns $6,000 a month before tax and pays $450 on a car loan, $300 on a student loan and $250 in card minimums. The proposed housing payment is $1,700. Total monthly debt would be $2,700, a DTI of 45 percent. Clearing the cards removes the $250 minimums, total debt falls to $2,450 and DTI falls to about 40.8 percent. The same payoff also cuts utilization, so it improves both tests at once.

Do not empty your savings, though. Lenders also want to see money for the down payment, closing costs and reserves. Our guide to mortgage closing costs explains what you need to have ready.

Credit score requirements

Minimum scores depend on the loan program, the lender and the rest of your file, so ask your lender for its own figures. As a reference point, Fannie Mae's Selling Guide lists a minimum score of 620 for manually underwritten fixed-rate loans and no set minimum score for loans assessed through its Desktop Underwriter system, which evaluates overall credit risk instead. Individual lenders may apply their own, stricter minimums.

Do not move money or open accounts before closing

From a few months before you apply until the day you close, keep your finances boring. The CFPB advises avoiding applications for credit cards, auto loans or other credit right before and during the mortgage process. It also notes that a lender may check your credit when you apply and again just before closing.

Do not open or co-sign any new credit, including store financing for furniture or appliances.
Do not make large unexplained deposits or shuffle money between accounts without a paper trail.
Do not change jobs, close accounts or dispute items without telling your loan officer first.

Rapid rescore through the lender

A rapid rescore is a service a mortgage lender can buy from the bureaus to update your report quickly after a documented change, such as a paid-down card balance or a corrected error. Experian says it is often completed within two to five days once the lender submits the documentation.

You cannot order one yourself. Only the lender can request it.
The lender cannot charge you the fee directly, according to Experian, though the cost may be reflected elsewhere in the price of the loan.
It only speeds up accurate updates. Equifax says it cannot undo a history of late payments and delinquent accounts.

Pre-approval timing and free help

Do your clean-up first, let it report, and then seek pre-approval. A pre-approval usually involves a hard inquiry and is valid for a limited time, so get it when you are ready to look at homes.

HUD-approved housing counselors give advice on buying a home and on credit issues, often at little or no cost, according to the CFPB. You can find one with the CFPB's search tool or by calling 1-855-411-2372.

Auto loan and personal loan specifics

Auto and personal loans are decided faster and with lighter checks than mortgages, so 30 to 90 days of preparation is usually enough.

Auto loans

Arrange financing before you visit the dealer. The CFPB recommends getting preapprovals from several lenders first, so you can compare the dealer's offer against them.
Keep the shopping period short. A dealer may send your application to several lenders. Inside the shopping window these are generally scored as one inquiry.
Look at total cost. A longer term lowers the payment but raises total interest. Compare APR and total paid, not only the monthly figure.
A larger down payment reduces the amount borrowed and can improve the terms offered.

Personal loans

Use prequalification. Many lenders show an estimated rate with a soft inquiry. The hard inquiry comes only when you formally apply.
Personal loan inquiries may not be grouped the way mortgage and auto inquiries are. Prequalify widely, then formally apply to one lender.
Check fees. An origination fee changes the real cost, so compare APRs.

For how lenders assess these applications, see our guide to how personal loans work.

What not to do

The fastest way to lose ground is to pay for a shortcut or to make a well-meant change at the wrong time.

Credit repair scams and your CROA rights

The FTC says credit repair companies cannot remove negative information that is accurate and current, and that anything they can legally do, you can do yourself for little or no cost. Under the Credit Repair Organizations Act (CROA), a credit repair company must give you a written contract that sets out the services, the total cost, how long results will take and any guarantees. You have three days to cancel without charge. It is illegal for the company to charge you before it has done the work.

The FTC's warning signs of a scam include a company that:

demands payment up front;
tells you not to contact the credit bureaus yourself;
tells you to dispute information you know is accurate;
tells you to lie on a credit or loan application;
suggests filing a false identity theft report;
does not explain your legal rights.

"Credit privacy numbers" are not a fresh start

Some sellers offer a "credit privacy number" (CPN) or tell you to apply for credit with an Employer Identification Number in place of your Social Security number. The FTC warns that these numbers are often stolen Social Security numbers, sometimes belonging to children, and that using a number other than your own to apply for credit will not get you the credit and could lead to fines or prison. There is no legal way to create a new credit identity.

Other common mistakes

Disputing everything. Mass disputes of accurate items waste time and can be rejected as frivolous.
Closing cards to "clean up". It reduces available credit and can raise utilization.
Debt settlement right before applying. The FTC warns that settlement programs often tell you to stop paying your creditors, which leads to late fees, penalties and credit damage, and that creditors do not have to agree to settle. Forgiven debt may also be taxable.
Co-signing for someone else. Their loan becomes your debt on paper.
Lying on the application. Misstating income, debts or identity on a loan application is fraud.

Wait or apply now: a decision table

Apply now if your file is clean and stable and you need the loan. Wait if a fixable problem is about to be fixed, or if a recent negative is still fresh and the loan is optional. Use the table as a guide.

Your situation	Lean toward	Why
Reports are accurate, utilization is low, no late payments in the past year	Apply now	Waiting adds little. Rates and prices can move against you in the meantime.
High card balances you can pay down within one or two statement cycles	Wait 30 to 60 days	Lower balances report quickly and help both score and DTI.
A clear error is on your report	Wait for the dispute result	Investigations generally take about 30 days.
A payment was missed in the last few months	Wait if the loan is not urgent	Recent late payments weigh most. Several clean months improve the picture.
Several new accounts or inquiries in recent months	Wait 3 to 6 months	New accounts need time to age, and inquiries fade.
Thin file with fewer than a few months of history	Wait 6 to 12 months and build	Scores need reported history. A secured card or credit-builder loan takes months to show.
Urgent need and no time to prepare	Apply, but compare carefully	Prequalify with soft pulls, compare APRs and plan to refinance later if your credit improves.

If you borrow at a higher rate now, refinancing later may be possible once your score improves, subject to fees.

Co-signers and joint applications

A co-signer with strong credit can help you qualify or get a better rate, but the co-signer takes on the whole debt, not a backup role. The FTC explains that a co-signer may have to pay up to the full amount plus late fees and collection costs, and that the creditor can collect from the co-signer without first trying to collect from the borrower.

The loan appears on the co-signer's credit report as their own obligation. If you pay late, their credit is damaged too. The FTC says getting released later is unlikely, because the lender has to agree.

A joint application is different: both people are borrowers and both usually share ownership. For mortgages, both incomes count, but so do both sets of debts and both credit files. Experian notes that lenders typically use the lower of the two applicants' middle scores, so adding a partner with weaker credit can raise the price.

After approval: protecting your score through closing

Approval is not the finish line. Until the loan has funded, the lender can re-check your credit and finances, and the CFPB notes that lenders may pull a report again just before closing.

Keep paying every bill on time, including small ones.
Keep card balances at or below the level they were at when you applied.
Do not open, close or co-sign anything.
Answer the lender's document requests quickly and tell your loan officer about any change in income or employment.

Once the loan has funded, you can return to normal, keeping the same habits: low balances and automatic on-time payments.

For UK readers

The principles are the same in the UK, but the system is different: there is no single universal score, each credit reference agency uses its own scale, and lenders score you with their own criteria. The ICO names the three main consumer credit reference agencies as Equifax, Experian and TransUnion.

Check all three files for free

You can get a statutory credit report from each agency without paying a fee. The ICO suggests looking for the phrase "statutory report" on each agency's website. If something is wrong, raise it with the agency and with the lender or utility company that supplied it. If neither will correct it, you can complain to the ICO. You can also add a notice of correction to your file to explain an entry.

Register on the electoral roll

Being on the electoral register at your current address helps lenders confirm your name and address. Experian UK says registering can improve your chances of being accepted for credit, and that the details typically appear on your report within about 30 days. If you are not eligible to vote, you can add a note saying you have documents proving your address.

Check your financial associations

A joint account or joint loan links your file to the other person's, and lenders may look at their record when assessing you. The ICO explains that when a joint account is closed and the link no longer applies, you can write to the agencies and ask for a disassociation.

Use soft-search eligibility checkers and space your applications

Experian UK explains that soft searches, including eligibility checks, are not visible to lenders and do not affect your score, while each hard search from a real application is recorded and most stay on your report for 12 months. Use an eligibility checker first, and space applications out: Experian UK suggests no more than one every three months as a general guide.

Other points carry over directly. Pay on time, and keep balances low: Experian UK suggests staying below about 30 per cent of your limit where you can. Missed payments, defaults and court judgments generally stay on a UK file for six years.

A note for readers in Canada

Canada has two main credit bureaus, Equifax and TransUnion, and the FCAC says you can order your credit report from each for free online, by mail or by phone. Checking your own report or score does not affect your credit.

The FCAC's advice matches the plan in this guide. Pay on time, which it calls the most important part of your score. Try to use less than 30 percent of your total credit limit. Keep older accounts open. Limit applications, since hard inquiries ("hard hits") affect your score and soft ones do not. When shopping for a car loan or mortgage, the FCAC suggests getting quotes from different lenders within a two-week period so the bureaus treat them as one inquiry. Late or missed payments can stay on a Canadian report for up to six years.

Pre-application checklist

Work through this list before you submit a formal application.

I pulled my reports from all three bureaus through the official free source and read every line.
I disputed real errors with both the bureau and the furnisher, and I have the written results.
My overall card utilization is under 30 percent, ideally under 10 percent, and no single card is near its limit.
I paid cards down before their statement closing dates, and the lower balances now show on my reports.
Every account is current, and autopay covers at least the minimum on all of them.
I validated any collection before paying and kept written records.
I have not applied for new credit or closed old cards, and will not until my loan has funded.
I know my debt-to-income ratio and have documents for my income and savings.
I asked the lender which bureau and score it uses, and whether prequalification is a soft pull.
I will compare several lenders inside a 14-day window.
I have not paid anyone an upfront fee to "repair" my credit.
For a mortgage: I will keep my accounts, job and balances stable until closing.

FAQ

How fast can I raise my credit score before applying for a loan?

The quickest changes come from paying card balances down before the statement date and from correcting errors. Lower balances can be reported within one monthly cycle, and disputes are generally investigated within about 30 days. Accurate negative items cannot be sped up.

Can I raise my credit score 100 points in 30 days?

Usually not, and no one can honestly guarantee it. A fast jump is only plausible if the score was held down by something quickly fixable, such as maxed-out cards or a serious error. Accurate late payments or collections take months of clean history to outgrow.

Does checking my own credit score lower it?

No. Checking your own report or score is a soft inquiry. The CFPB says the credit reporting companies do not treat it like a lender's inquiry, and it has no effect on your scores.

What credit score do I need to get a mortgage?

There is no single number. It depends on the loan program, the lender and the rest of your application. Fannie Mae's Selling Guide lists 620 for manually underwritten fixed-rate loans and no set minimum for loans assessed by its automated system, and lenders may set their own minimums. Ask each lender for its requirements.

Which credit score do mortgage lenders use?

Most still use older FICO versions: FICO Score 2 from Experian, FICO Score 4 from TransUnion and FICO Score 5 from Equifax. Experian says lenders may use the middle of the three and, for joint applicants, typically the lower of the two middle scores. These can differ from the score in your banking app.

Should I pay off my credit cards before applying for a mortgage?

Paying them down usually helps twice: it lowers utilization, which can raise your score, and it removes minimum payments from your debt-to-income ratio. Pay before the statement closing date, and keep the money you need for the down payment and closing costs.

Will paying off a collection raise my score?

It depends on the model. Experian says FICO Score 9, FICO 10 and VantageScore 3.0 and 4.0 disregard paid collections, while FICO Score 8 and older versions still count them. The collection stays on your report for seven years either way.

Does shopping around for a loan hurt my credit?

Very little, if you do it in a short period. The CFPB says mortgage inquiries within a 45-day window are recorded as a single inquiry, and auto loan inquiries within 14 to 45 days generally count as one. Keeping all quotes inside 14 days is the safest approach.

Should I close unused credit cards before applying?

No. myFICO warns that closing unused cards as a short-term strategy can lower your score by reducing your available credit. If you want to close a card, do it after your loan has funded.

Is it worth paying a credit repair company?

Rarely. The FTC says these companies cannot remove accurate, current negative information, and that you can do anything legal they do yourself for little or no cost. The law gives you a written contract, a three-day right to cancel and protection from upfront fees.

What is a rapid rescore and can I ask for one?

It is a paid service that lets a mortgage lender have your report updated in days after a documented change, such as a paid-down balance. Experian says only the lender can request it and that the lender cannot charge you the fee directly. It does not remove accurate negative information.

How long do late payments stay on my credit report?

In the US, accurate negative information, including late payments, can generally be reported for up to seven years, and bankruptcies for up to ten, according to the CFPB. The effect on your score fades as the late payment ages and as you add on-time payments.

Bottom line

Improving your credit before a loan application is mostly about order and timing. Read all three reports, fix what is wrong, get reported balances low, keep every payment on time, and then leave your file alone until the loan has funded.

Be realistic about what time can and cannot do. Errors and balances can change within one or two reporting cycles. Accurate late payments and collections fade slowly. If the loan is large and the timing is yours to choose, a few extra months of clean history is usually the cheapest improvement available.
