How long is a mortgage preapproval good for?
Usually 60 to 90 days, depending on the lender. If it expires, the lender can refresh it with updated pay stubs and bank statements. Keep the current letter uploaded in ListingCraft for Buyers so the listing agent always sees the latest one.
You can replace the letter in ListingCraft for Buyers Settings at any time, and ListingCraft for Buyers reminds you when no letter is on file.
