Make sure the new title is correct. The fact is, most people never see their deed before it's recorded at the county court house, says Gumbinger. He recommends that you ask the lender if you can review the title to the property before it gets filed, so that you can make sure it's correct.
When lenders offer a "no-cost" loan, they may include a prepayment penalty to discourage you from refinancing within the first few years of the loan. Ask the lender offering a no-cost loan to explain all the fees and penalties before you agree to these terms.
Ask the lender or broker for a comparison of the up-front costs, principal, rate, and payments with and without this rate trade-off.
If your new mortgage rate seems too good to be true then it probably is. Check for hidden fees in your mortgage that will make up that suspicious difference.
