The borrower pays closing costs on an FHA Streamline Refinance. Unlike other types of refinances, you cannot roll these costs into your loan amount. FHA Streamline closing costs are typically the same as other mortgages: 2 to 5 percent of the mortgage amount, which would equal $3,000 to $7,500 on a $150,000 loan. The difference is that you don’t have to pay for an appraisal on an FHA Streamline, which could save about $500 to $1,000 in closing costs.
