Mortgage pre-approval is a lender’s written, conditional statement of how much it is willing to lend you, based on your credit report, income, debts and savings. You get one by checking your own credit first, working out your debt-to-income ratio, sending the lender your documents, and comparing two or three letters issued inside the same 45 days.

The letter is what makes a seller take an offer seriously. It is not a loan. Most guides stop at the paperwork list; this one also shows the limits lenders actually apply, how far today’s rates shrink the number on the letter, and, from 2025 federal mortgage data, the reasons applications were turned down.

What lenders check, and the limits they use

Where did the 43% figure go? For years “43%” was the number everyone quoted, because the federal General Qualified Mortgage definition capped DTI there. The CFPB’s final rule issued 10 Dec 2020 removed that cap and replaced it with a price test: under 12 CFR 1026.43(e)(2)(vi) today, a first-lien loan above the rule’s size threshold (written as $110,260 in the rule and raised for inflation each year) qualifies only if its APR is less than 2.25 points above the average prime offer rate.

Lenders still have to consider DTI or residual income; they just no longer face a single federal ceiling. That is why the practical limits now come from the loan program, as in the table.

Pre-approval vs pre-qualification: what the CFPB says

The top-ranking guides draw a hard line: pre-qualification is a quick estimate, pre-approval is the verified version. The Consumer Financial Protection Bureau is blunter. It says lenders use the two words differently, that some lenders call a letter “prequalification” and others call the same thing “preapproval”, and that the label tells you little about the process behind it. Both kinds of letter, it says, fall short of a firm loan offer.

So judge the letter by what it contains rather than what it is called. A useful one says what the lender verified (income, assets, a credit report), the amount, the loan type, the expiry date and the conditions still open, such as an appraisal or a final income check. The CFPB adds one protection worth knowing: a lender that reviews your credit and turns down a prequalification or preapproval request must send you an adverse action notice, which gives you the reason in writing.

Before you start

Pre-approval goes faster and says more when the documents are ready before the first call. Have these in hand:

• Two recent pay stubs plus two years of W-2s or tax returns. Self-employed? Bring the full returns with every schedule.
• Two months of bank and investment statements, every page, so the lender can see the down payment and closing money and where it came from.
• A written list of every monthly debt payment: car loans, student loans, card minimums, child support. These are the numbers the lender will divide by your income.
• Your credit reports from all three bureaus, read line by line before a lender pulls them.

The arithmetic behind each rate quote is explained on interest rates; this page assumes you know what an APR is.

The steps

1. Pull your three credit reports and dispute any error before applying.

A wrong late payment or a balance that was paid off can lower the score a lender prices you on. Disputes take time, so this comes first.

2. Add every monthly debt payment and divide by gross monthly income.

That is your DTI before the new loan. Then add the expected housing payment, including property tax and insurance, and divide again. Compare the result with the limits in the table above.

3. Price the payment at today’s rate and at one point higher.

The mortgage payment calculator does the formula. If the higher payment would not fit your budget, the letter’s top amount is not your target.

4. Collect pay stubs, W-2s or returns, and two months of statements into one folder.

Missing pages are what turn a same-day answer into a week. In 2025, 7.1% of denied purchase applications cited an incomplete application.

5. Apply with two or three lenders inside one 45-day window.

The CFPB says multiple mortgage credit checks within 45 days are recorded as a single inquiry, so comparing lenders costs no more credit damage than asking one.

6. Compare each letter’s amount, loan type, expiry date and open conditions.

The letter with the biggest number is not automatically the best. Ask each lender for an official Loan Estimate before you commit, so rates and fees sit side by side on the same form.

7. Keep your credit and job unchanged until the loan closes.

A new car loan, a new card or a job change can undo the approval, because lenders can re-check credit, income and employment before closing.

How to tell it worked

You are done when you hold at least one letter that names a dollar amount, a loan type, an expiry date and its remaining conditions, and that amount is no more than the loan your own DTI math allows with the rate set 1 point higher. If you applied with more than one lender, the first and last credit pulls should sit within 45 days of each other.

A worked example: what each DTI limit allows

Take a household earning $9,000 a month before tax, with $650 a month of other debts and an assumed $550 a month of property tax and insurance. The rate is Freddie Mac’s weekly 30-year average of 7.18% for 5 Nov 2026. These inputs are an example, not a quote.

Each step is the same three moves: multiply income by the limit, subtract the other debts and the tax and insurance, then turn what is left into a loan with the standard 360-month payment formula. Moving from a 36% file to a 50% file adds $185,996 of borrowing on the same income, which is why a letter’s amount says more about the program than about what is comfortable.

Rates move the answer too. At 45%, a rate half a point higher, 7.68%, cuts the loan from $420,705 to $400,517, a drop of $20,188 with nothing else changed.

The original data

Why lenders said no in 2025. The Home Mortgage Disclosure Act requires most lenders to report every application. We took the 2025 nationwide file and kept first-lien, owner-occupied home-purchase applications on 1-4 unit homes, leaving out business-purpose, reverse and open-end loans. That leaves 2,984,281 loans made and 502,644 denied, a denial rate of 14.4% (denials divided by denials plus loans made). (Across every home-purchase application reported, it was 607,818 denied against 3,592,033 made, 14.5%.)

A lender can list up to four reasons per denial. Each application counts once under every reason it cites, so the shares add up to more than 100%, and the 6,432 denials (1.3%) filed by lenders exempt from reporting reasons stay in the 502,644 total. The share of the 502,644 denials citing each:

• Debt-to-income ratio: 39.2%. The most common reason, and the one a borrower can measure before applying.
• Credit history: 35.7%.
• Insufficient cash for the down payment or closing costs: 16.8%.
• Other: 14.9%; collateral (the home’s value or condition): 10.2%; unverifiable information: 9.6%; incomplete application: 7.1%; employment history: 4.1%.

How high was the DTI on those denials? Of the denials citing DTI that also report the ratio, 192,283 in all, 85.4% had a DTI of 50% or more and 56.9% were above 60%. Only 6.5% were at 43% or below. Read that with care: it shows who was refused, not where every lender draws its line. It does fit the table above, where 50% is the automated ceiling.

The denial rate also differs by loan type in the same sample: 15.8% for conventional loans, 13.1% for FHA, 13.6% for USDA and 8.4% for VA. The applicant pools differ, so those gaps describe who applied as much as how strict each program is.

How rates change the letter. Using Freddie Mac’s weekly 30-year rate from 7 Jan 2016 to 5 Nov 2026 (566 weeks), we worked out the loan a fixed $2,500 monthly principal-and-interest payment repays over 30 years.

The same payment buys 40.5% less loan today than at the 2021 low. A pre-approval issued when rates were lower, or quoted at a rate you have not locked, can overstate what the payment you planned for will buy.

When it fails

The appraisal comes in low. Collateral was cited on 10.2% of 2025 denials. The letter assumed a home worth the price; if the appraiser disagrees, the loan shrinks or the buyer brings more cash.

Something changes after the letter. New debt, a missed payment or a job change all show up when the lender checks again before closing, and the conditional approval no longer holds.

The rate moves before you lock. On the worked example, half a point cost $20,188 of borrowing power. A letter quotes today’s market; it does not hold today’s rate.

The letter expires. It carries a date. An offer made after it lapses needs a fresh review, often a new credit pull.

The documents do not match the application. Unverifiable information was cited on 9.6% of denials. Income stated one way on the application and another way on the tax return is a common route there.

Questions people ask

Does pre-approval hurt your credit?

The lender’s credit check is recorded as an inquiry, which the CFPB says typically has a small negative effect. Several mortgage checks within 45 days count as one inquiry, and checking your own credit has no effect.

Can you be denied after pre-approval?

Yes. The letter is conditional. The loan is approved only after the appraisal, a final review of income and assets, and a last credit check.

How long does a pre-approval letter last?

As long as the date printed on it. No federal rule sets the length; the three lender and brokerage guides we read in November 2026 quoted 30 to 90 days. After it lapses, expect fresh documents and often a new credit pull.

How many lenders should you get pre-approved with?

Two or three is enough to compare rates and fees, and the 45-day rule means it costs no more credit damage than one. Ask each for an official Loan Estimate.

What credit score do you need?

It depends on the program and the lender. Fannie Mae requires 620 on a manually underwritten fixed-rate loan and no minimum for a loan run through its automated system; VA sets no minimum at all.
