How to Get Pre-Approved for a Mortgage
A pre-approval letter shows sellers you are a serious buyer and locks in the loan amount you qualify for. Learn the 5-step process, what documents lenders require, and how to protect your credit during the process.
What pre-approval is
A mortgage pre-approval is a written commitment from a lender stating the loan amount, rate type, and loan program you qualify for — based on verified income, assets, and credit. It is not a guarantee to lend, but it gives sellers confidence you can close.
The 5-step pre-approval process
- Step 1 Check your credit report and score
Pull your free credit reports from all three bureaus at AnnualCreditReport.com. Look for errors, collections, or derogatory marks. Dispute any inaccuracies before applying — corrections can take 30–60 days. Conventional loans typically require a minimum 620 score; FHA allows 580 with 3.5% down.
- Step 2 Calculate your DTI before a lender does
Add up all monthly minimum debt payments (car loans, student loans, credit card minimums, other installment debt). Divide by your gross monthly income. If your DTI is above 43%, pay down high-minimum debts before applying. Getting pre-approved with a high DTI often means a lower loan amount or a higher rate.
- Step 3 Gather your documents
Most lenders require: 2 years of W-2s or tax returns (self-employed: 2 years of 1099s + business returns), 2 most recent pay stubs, 2–3 months of bank statements, investment/retirement account statements, government-issued ID, and landlord contact for rental history if applicable.
- Step 4 Shop at least 3 lenders within a 14-day window
Rate shopping is protected: multiple mortgage hard inquiries within 14–45 days count as one. Compare APR, origination fees, and points — not just the rate. A lower rate with high origination fees may cost more if you sell or refinance within 5 years. Use the CFPB Loan Estimate form as your apples-to-apples comparison tool.
- Step 5 Protect your credit until closing
After pre-approval, do not open new credit accounts, do not make large purchases on credit, and do not change jobs if avoidable. Lenders re-pull your credit just before closing. A new car loan or credit card can increase your DTI enough to jeopardize approval.
Documents you will need
| Document | How much | Notes |
|---|---|---|
| W-2s / tax returns | 2 years | 1099 + business returns if self-employed |
| Pay stubs | Most recent 2 | YTD earnings must align with W-2s |
| Bank statements | 2–3 months | All accounts; sourced large deposits explained |
| Investment/retirement statements | Most recent | Used for asset / reserves verification |
| Government-issued ID | Current | Driver license or passport |
| Rental history | 12–24 months | If renting — landlord name and contact |
DTI thresholds by loan type
Your debt-to-income ratio is the single biggest factor in determining how much you can borrow. Here are the standard limits:
Conventional (Fannie/Freddie)
Standard max: 43–45% back-end DTI. With strong credit and reserves, automated underwriting may approve up to 50%.
FHA
Standard max: 43% back-end DTI. With compensating factors (high credit score, reserves), up to 57% is possible.
VA
No hard DTI cap. Lenders typically apply a 41% soft limit. Residual income requirement is the primary constraint.
Jumbo
Strictest. Most lenders cap at 43% DTI with 12+ months reserves regardless of credit score.
What to avoid after pre-approval
- Do not open any new credit accounts (cards, car loans, personal loans)
- Do not make large purchases on credit — even furniture for the new home
- Do not change jobs or go from W-2 to self-employed
- Do not co-sign a loan for someone else
- Do not make large cash deposits without documenting the source
Lenders pull a final credit report just before closing. Changes that raise your DTI or lower your credit score can delay or kill the transaction.
Common questions
How long does mortgage pre-approval take?
Most lenders issue a pre-approval letter within 1–3 business days after you submit a complete application with all required documents. Some online lenders offer same-day or next-day conditional approvals, though these may be subject to manual review. If your file has complications (self-employment, multiple income sources, past credit issues), expect 3–5 business days. The CFPB Loan Estimate must be issued within 3 business days of a complete application.
How long is a pre-approval letter valid?
Typically 60–90 days. After that, the lender will need to verify that your income, employment, and credit have not changed before reissuing. If you are still house-hunting at 60 days, contact your lender proactively — a quick update is easier than restarting. Note that pre-approval letters are not commitments to lend; underwriting still happens after you are under contract.
Does getting pre-approved hurt my credit?
A pre-approval triggers a hard inquiry, which typically reduces your score by fewer than 5 points and recovers within a few months. The good news: multiple mortgage inquiries within a 14–45 day window are treated as a single inquiry by FICO and VantageScore models. So shopping multiple lenders during that window costs no additional points. Checking your own credit (a soft pull) before applying does not affect your score at all.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is an informal estimate based on self-reported information — no credit check, no document verification. It gives you a rough borrowing range but carries little weight with sellers. Pre-approval involves a hard credit pull and verification of income, assets, and employment. Sellers and their agents treat pre-approval letters as meaningful evidence that the buyer can close. In competitive markets, many sellers will not consider offers without a pre-approval letter.
Can I get pre-approved with student loans?
Yes. Student loans are included in your debt-to-income ratio (DTI), but they do not disqualify you unless DTI exceeds the lender's limit. If your loans are in income-based repayment (IBR) with a $0 payment, lenders typically impute a payment of 0.5%–1% of the outstanding balance per month. On $80,000 in student loans, that imputed payment could be $400–$800/month in your DTI even if your actual payment is $0. The FHA uses 0.5%; conventional (Fannie Mae) uses the actual payment or 1% if $0.
