How long does a pre-approved home loan last?

A pre-approval letter is typically valid for 60 to 90 days, after which you may need to reapply or update your documents if your financial situation has changed.

Does getting pre-approved for a mortgage hurt my credit score?

The initial credit inquiry for pre-approval may cause a small, temporary dip in your credit score (usually fewer than 5 points). However, multiple mortgage inquiries within a 14- to 45-day window are treated as a single inquiry by credit scoring models.

Can I get pre-approved with a low credit score?

Yes, some loan programs accept lower credit scores. For example, FHA loans may allow scores as low as 580 with a 3.5% down payment, and certain conventional loans accept scores starting at 620. However, a lower score typically results in a higher APR and stricter terms.

Learn what a pre-approved home loan means, how to get pre-approved for a mortgage, and the steps to strengthen your application with a trusted lender.

A pre-approved home loan is a conditional commitment from a lender to lend you a specific amount of money to buy a home, based on an initial review of your income, assets, and credit. Getting pre-approved for a mortgage is the critical first step that shows sellers you are a serious buyer and helps you understand your budget before you start house hunting. This guide explains how to get pre-approved, what lenders look for, and how to prepare for the process.

What Is a Pre-Approved Home Loan?

A pre-approval is more rigorous than a pre-qualification. During pre-approval, a lender verifies your financial documents—such as pay stubs, tax returns, and bank statements—and pulls your credit score. Based on this review, the lender issues a pre-approval letter stating the loan amount and loan term you qualify for. This letter is valid for a set period, typically 60 to 90 days. Keep in mind that pre-approval is not a final loan commitment; final approval depends on the property appraisal and underwriting.

How to Get Pre-Approved for a Home Loan: 5 Key Steps

Check your credit score and report. Your credit score directly affects the APR and loan terms you are offered. Request a free annual credit report from each of the three major bureaus, and dispute any errors you find. A score of 620 or higher is generally needed for conventional loans, while FHA loans may accept lower scores.
Gather financial documents. Lenders typically require: two years of W-2s or tax returns, recent pay stubs, bank statements (last 2–3 months), government-issued ID, and proof of any additional income or assets.
Calculate your down payment and debt-to-income ratio. Your down payment can range from 3% to 20% or more, depending on the loan type. Lenders also look at your debt-to-income ratio—ideally below 43%—which includes your future mortgage payment, credit cards, car loans, and other debts.
Compare lenders and apply. Submit a loan application with a lender of your choice. You can apply with multiple lenders within a short window (usually 14–45 days) to compare offers without hurting your credit score multiple times, as credit bureaus treat these as a single inquiry.
Receive your pre-approval letter. Once verified, the lender provides a pre-approval letter stating the loan amount and estimated APR. Review the details carefully—this is not a guarantee of final approval, but it is a powerful tool when making an offer.

What Lenders Evaluate During Pre-Approval

Lenders assess several factors to determine your pre-approved home loan amount and terms. The table below summarizes the key elements:

Factor	What Lenders Look For	Typical Requirement
Credit Score	Payment history, credit utilization, length of credit	620+ (conventional); 580+ (FHA)
Income Stability	Consistent employment, sufficient income to cover payments	2+ years at same job or stable industry
Down Payment	Cash available for purchase plus closing costs and escrow reserves	3%–20% of purchase price
Debt-to-Income Ratio	Total monthly debt payments divided by gross monthly income	Below 43%
Assets	Bank accounts, investments, retirement funds	Sufficient for down payment and 2–6 months of reserves

This is general guidance; each lender may have different criteria. Always ask your lender about specific requirements.

Common Mistakes to Avoid When Getting Pre-Approved

Applying before checking your credit. Errors on your credit report can lower your score or disqualify you. Fix them first.
Changing jobs or income sources. Lenders prefer stability. Avoid switching jobs or becoming self-employed right before or during pre-approval.
Making large purchases or opening new credit. New credit cards, car loans, or other debts can raise your debt-to-income ratio and lower your credit score, potentially reducing your pre-approved amount.
Not shopping around. Different lenders offer different APRs, fees, and loan terms. Comparing multiple offers can save you thousands over the life of the mortgage.
Ignoring closing costs and escrow. Pre-approval focuses on the loan amount, but you will also need funds for closing costs (typically 2%–5% of the loan) and an escrow account for taxes and insurance.

What to Do After Pre-Approval

Once you have your pre-approved home loan letter, you can confidently shop for homes within your budget. Keep your financial situation stable—do not make major purchases or change jobs—until your loan closes. When you find a home and make an offer, the seller will see your pre-approval as a sign of reliability. After your offer is accepted, the lender will order an appraisal and begin final underwriting. Stay in close contact with your loan officer and promptly provide any additional documents requested. This stage may also involve setting up escrow for property taxes and homeowners insurance. Remember, pre-approval is a strong step, but final approval is subject to the property meeting the lender's standards.
