How Long Does a Mortgage Pre-Approval Last?


When you’re house hunting, getting pre-approved for a mortgage is an essential first step. But how long does that pre-approval actually last? Whether you’re browsing homes for sale in Austin, TX or planning to make an offer on a home in Seattle, WA, knowing the timeline for a pre-approval can help you plan your next move and avoid surprises.

This Redfin article explains how long mortgage pre-approvals are valid, what happens when they expire, and how to renew one if needed.

What is a mortgage pre-approval?

A mortgage pre-approval is a letter from a lender stating how much they’re willing to lend you to buy a home. It’s based on a detailed review of your financial situation, including:

  • Your credit score
  • Income and employment history
  • Debt-to-income (DTI) ratio
  • Assets and liabilities

Unlike pre-qualification (a less formal estimate), pre-approval involves a hard credit check and document verification. Sellers often view buyers with a pre-approval letter as more serious and reliable.

How long is a pre-approval good for?

Most mortgage pre-approvals are valid for 60 to 90 days, but this can vary by lender and market conditions. Here’s a quick breakdown:

Lender Typical Validity Period
Big Banks 60–90 days
Credit Unions 60–120 days
Online Lenders 30–90 days

This timeframe exists because your financial situation (credit score, income, debt) and market conditions can change over time.

Why do pre-approvals expire?

Lenders set expiration dates on pre-approvals for two main reasons:

  • Financial changes: Your credit score, income, or debts may change in a few months.
  • Market conditions: Interest rates and loan programs fluctuate, impacting how much you can borrow.
