A mortgage pre-approval typically lasts for 60 to 90 days. The exact duration can vary depending on the lender and market conditions. This timeframe reflects the validity of the financial information provided and the lender’s preliminary assessment of your creditworthiness.

After the pre-approval period expires, you may need to update your financial documents and reapply for a new pre-approval if you haven’t yet found a property or if your financial situation has changed. This ensures that your pre-approval accurately reflects your current financial status.
