Should I share my preapproval letter when I request a showing?
Often it helps, because it shows the listing agent you are a serious buyer. You do not have to reveal your full approval amount; lenders can issue a letter for the price of the home. In ListingCraft for Buyers, you choose per request whether to attach your letter.
The agent sees a "Preapproval on file" badge either way when you have uploaded a letter, and opens the letter only if you share it.
