How to Get Pre-Approved for a Mortgage
Pre-approval is the step that turns you from a browser into a buyer an agent will schedule showings for. Here is exactly what to gather, what credit score each loan type needs, how long the process takes, and how long the letter stays good.
The Pre-Approval Document Checklist
Every lender asks for roughly the same package. Gather it before you apply and a pre-approval that could drag on for two weeks usually lands in two days.
Income
- Your two most recent pay stubs (covering roughly the last 30 days)
- W-2 forms for the last two years
- Last two years of federal tax returns, including every schedule
- Award letters for Social Security, pension, or disability income
Assets
- Two months of statements for every checking and savings account
- Recent statements for brokerage and retirement accounts
- A signed gift letter, plus the donor's bank statement, if family is helping with the down payment
Identity & credit
- Government-issued photo ID
- Social Security number, so the lender can pull your credit
- Written explanations for any recent late payments, collections, or large deposits
If it applies to you
- Self-employed: two years of business and personal returns, a year-to-date profit-and-loss statement, and any K-1s or 1099s
- Renting now: your landlord's contact information and 12 months of rent history
- Own other property: the mortgage statement, tax bill, insurance policy, and HOA dues
- Divorced: the decree, plus any child support or alimony orders
Two habits save the most time. Send complete statements — every page, including the blank last one, since lenders reject partial PDFs. And be ready to source any deposit that is not a paycheck: underwriters have to document where the money came from, and an unexplained $5,000 transfer will hold up your file.
Pre-Approval vs Pre-Qualification
The two words sound interchangeable and are not. The difference is whether anyone checked your numbers.
| Pre-Qualification | Pre-Approval | |
|---|---|---|
| What the lender checks | Numbers you state, unverified | Credit report, pay stubs, tax returns, bank statements |
| Credit inquiry | Soft pull or none | Hard pull |
| How long it takes | Minutes, often online | One to three business days after documents arrive |
| What you get | A ballpark estimate | A letter stating a specific loan amount |
| Weight with sellers | Little to none | Expected with any competitive offer |
Neither one is a commitment to lend. Even a pre-approval is conditional: the file still has to clear full underwriting, and the home has to appraise for at least what you agreed to pay. Some lenders offer a stronger version — marketed as an underwritten or verified approval — where an underwriter reviews the file up front rather than after you go under contract. It takes longer to get and makes an offer harder to beat.
Credit Score Thresholds by Loan Type
The program minimum and the score your lender will actually accept are two different numbers. Lenders layer their own requirements — called overlays — on top of the federal floor.
| Loan type | Program minimum | What lenders usually want |
|---|---|---|
| Conventional | 620 | 740+ for the best rate and lowest PMI |
| FHA | 580 with 3.5% down; 500 with 10% down | 620–640 at most lenders |
| VA | No VA-set minimum | 580–620 |
| USDA | No USDA-set minimum | 640 for streamlined automated underwriting |
| Jumbo | Set by the lender | 700+, with larger cash reserves |
Score is only half the picture. Lenders pair it with your debt-to-income ratio, and the classic guideline is the 28/36 rule: housing under 28% of gross monthly income, total debt under 36%. Conventional loans often approve up to a 43% back-end DTI, and FHA can stretch to 50% with compensating factors like strong reserves. If your score is borderline, paying down a revolving balance before you apply moves both numbers at once.
The Pre-Approval Process, Step by Step
- Check your credit first. Pull your reports and fix errors before a lender sees them. A disputed collection takes weeks to clear, and you want that done before the hard inquiry, not after.
- Know your own number.Run the affordability math yourself so the lender's figure confirms your plan instead of setting it. Walking in with a target keeps you from shopping at the top of someone else's range.
- Gather the documents above. This is the part that actually determines your timeline.
- Apply to three or four lenders inside two weeks. Each must send a Loan Estimate within three business days of your application. Clustering the applications keeps the inquiries scored as one.
- Compare the Loan Estimates line by line. Look past the rate at origination charges, points, and lender credits. Two lenders quoting the same rate can differ by thousands in fees.
- Get the letter. It states a maximum loan amount and an expiration date. Ask the lender to reissue it at your offer price rather than your maximum — handing a seller a letter for $50,000 more than you offered tells them exactly how much room you have.
Only the credit pull and the letter are visible to sellers. Everything that determines how fast this goes happens in steps one through three.
How Long a Pre-Approval Lasts
Most letters are valid for 60 to 90 days. The clock exists because the file behind the letter ages: credit reports and pay stubs go stale, and an underwriter cannot rely on a three-month-old snapshot of your finances.
Renewing is normally a document refresh — new pay stubs, updated bank statements, sometimes a fresh credit pull — rather than starting over. If your search runs long, ask the lender to re-pull inside the same 45-day shopping window when possible, so the inquiry folds into the original cluster.
One thing the expiration date hides: the letter is priced to the rate environment on the day it was issued. If rates rise while you shop, the same income supports a smaller loan, and a renewed letter may come back with a lower maximum than the original. That is not a change in your finances — it is arithmetic.
What Can Void a Pre-Approval
Underwriting re-checks your credit and employment shortly before funding. Between the letter and the keys, change nothing financially:
- No new credit. A card opened for the appliances, or a financed couch, adds a monthly payment to your DTI and a fresh inquiry to your report.
- No car loan. The single most common deal-killer. A $500 payment can erase tens of thousands of dollars of borrowing power.
- No job change. Especially not from salaried to self-employed or commission — lenders want a two-year history in the new structure.
- No large unexplained deposits. Money that appears without a paper trail has to be sourced, and cash generally cannot be.
- No moving money between accounts right before closing unless you can document both ends of the transfer.
Also keep saving. Pre-approval covers the loan, not the cash you bring to the table — your down payment plus closing costs, which typically run 2% to 5% of the purchase price.
Frequently Asked Questions
What do I need for a mortgage pre-approval?
At minimum: your two most recent pay stubs, W-2s from the last two years, two years of federal tax returns with all schedules, two months of statements for every bank and brokerage account, a photo ID, and your Social Security number for the credit pull. Self-employed borrowers add a year-to-date profit-and-loss statement and business tax returns. If any of the down payment is a gift, you also need a signed gift letter and the donor's bank statement showing the funds.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is an estimate based on numbers you tell the lender, with nothing verified — it takes minutes and carries little weight with sellers. Pre-approval means the lender pulled your credit and checked your income and assets against real documents, then issued a letter stating how much they will lend. Sellers and listing agents take pre-approval letters seriously; in competitive markets many will not consider an offer without one.
How long does it take to get pre-approved for a mortgage?
The application itself takes under an hour. Once your documents are in the lender's hands, many lenders issue a letter within one to three business days. What actually stretches the timeline is gathering paperwork — self-employed borrowers, people with multiple income sources, and anyone who needs to explain a large deposit should expect it to take longer.
What credit score do I need to get pre-approved?
It depends on the loan. Conventional loans generally start at 620. FHA allows 580 with 3.5% down, or 500 with 10% down, though most lenders add their own overlays requiring 620 to 640. VA and USDA set no federal minimum, but lenders commonly want 580 to 640. Jumbo loans usually require 700 or higher. The best pricing on a conventional loan goes to borrowers above 740.
How long does a mortgage pre-approval last?
Most pre-approval letters are valid for 60 to 90 days, because the credit report and income documents behind them go stale. Renewing one is usually a document refresh rather than a full reapplication. Remember that the letter reflects the rate environment when it was issued — if rates move before you go under contract, the amount you qualify for moves with them.
Does getting pre-approved hurt your credit score?
A pre-approval requires a hard credit inquiry, which can shave a few points off your score temporarily. Shopping several lenders does not multiply the damage as long as you cluster the applications: credit scoring models count multiple mortgage inquiries made inside one shopping window as a single inquiry, and that window runs 14 to 45 days depending on the model. Keeping your applications inside about two weeks stays safe under every version.
Can a mortgage pre-approval be denied later?
Yes. A pre-approval is not a commitment to lend. The lender re-verifies your credit and employment before closing, and the loan still has to clear full underwriting and an appraisal that supports the purchase price. Opening a new credit card, financing furniture or a car, changing jobs, or moving large sums between accounts between the letter and the closing table are the most common reasons an approved file falls apart.
Should I borrow the full amount I am pre-approved for?
Usually not. Pre-approval tells you the ceiling a lender is willing to underwrite, not the payment you will be comfortable making. The letter is built from your gross income and the debts that show up on a credit report — it does not know about childcare, retirement contributions, commuting costs, or the maintenance a house needs. Many buyers shop 10% to 20% below their pre-approved maximum on purpose.
Can I get pre-approved with more than one lender?
Yes, and you should. Comparing three or four Loan Estimates side by side is the most reliable way to lower your rate and fees, since origination charges and lender credits vary meaningfully between lenders on the same file. Each lender must send you a Loan Estimate within three business days of receiving your application, which makes the offers easy to compare line by line.
