What’s being eliminated is an interest-rate charge. For FHA borrowers that pay off their mortgage before the end of the month, the lender is allowed to charge to the borrower the interest rate costs on the loan from the day the loan is retired until the last day of the month. So, if a borrower paid off the loan on Sept. 10, the penalty would be 20 days of interest payments. That can be hundreds of dollars. Once the change takes effect, on Jan. 21, 2015, lenders will no longer be able to apply that interest charge to the borrower.
