Pre-Approval Letters are valid for as long as the market and the information you provided your mortgage lender remains unchanged.
For example, the loan program you received is still available and you continue your employment receiving the same income or higher, your down payment remains the same or higher and your Credit Score remains the same or higher.
This could mean a few hours, a few weeks or a few months, it really is dependent on a number of factors which is why you’ll want to keep your lender informed throughout your home buying journey.
With this being said, we recommend updating your Pre-Approval Letter every 30 days and you can easily do so here
