While you can roll closing costs into your loan when you refinance a mortgage, you typically can’t when you’re buying a new home. However, it may be possible to get the lender to cover closing costs in exchange for giving you a higher interest rate on your mortgage. Be cautious about exercising this option, however, as increasing your interest rate would result in higher monthly payments and interest charges. You may be better off covering closing costs upfront rather than increasing the interest rate on your mortgage.
