So you found your dream house, saved your money and the seller asked for your approval letter from your lender. You realize that, even though you'll have no problem in finding a home loan, you somehow hadn't' gotten around in applying for a loan.
Most people simply pick up the phone and call a lender.
By logging onto the Internet you can find an endless array of lenders begging you to visit their site. Many offer instant loan approvals and by completing some information you can obtain your approval notice within moments after entering in your personal data. But a pre-approval is not a loan commitment. While your credit report could have been reviewed automatically and with your permission from an online site, the facts are that verification and other checks are required before a new mortgage is issued. At least you will have spoken with a lender and gotten an idea regarding what you can afford and what loan choices might be best for you.
