4 rules mortgage lenders must follow

Percent sign in trap

The Federal Reserve's disclosure requirements for mortgages are designed to protect consumers from nonrefundable fees and higher interest rates.

The rules, which took effect in 2009, also apply to home equity loans but not home equity lines of credit.

They require lenders to:

The three days doesn't start until the borrower receives the new GFE (or three days after the new good faith estimate is mailed), giving borrowers a total of six days from the postmark date.

Those rules make it impossible for lenders to spring a higher interest rate on customers at the closing when they're under intense pressure to proceed with the purchase regardless of the cost.

They also prevent mortgage brokers from deliberately underestimating interest rates to collect hundreds of dollars in nonrefundable fees before revealing the true cost of the home loan in the GFE.

The one exception to the rule: Lenders don't have to provide a new GFE if the interest rate goes down.

If you're applying for a home loan, here are the 8 critical questions your good faith estimate should answer and 6 smart moves to save on closing costs.
