What is preapproval?
Buyers Answers

"Preapproval" means you have met with a loan officer, your credit files have been reviewed and the loan officer believes you can readily qualify for a given loan amount with one or more specific mortgage programs. Based on this information, the lender will provide a preapproval letter, which shows your borrowing power. You can visit as many lenders as you like and get several preapprovals, but keep in mind that each one carries with it a new credit check, which will show up on future credit reports.

Although not a final loan commitment, the preapproval letter can be shown to Realtors when bidding on a home. It demonstrates your financial strength and shows that you have the ability to go through with a purchase. This information is important to owners since they do not want to accept an offer that is likely to fail because financing cannot be obtained.
