First up: What are closing costs for a refinance?
Refinancing a mortgage takes time and has a few moving parts and help from several different people. Closing costs cover the expense of the process, and generally include fees for:
Application, origination and/or underwriting
Appraisal, home inspection and/or property survey
Title search
Title insurance
Property recording
Transfer taxes, if applicable
Prepaids, like interest, homeowners insurance or property taxes
Discount points to lower your interest rate, if applicable
You can typically pay closing costs upfront at closing time, or roll them into your refinance if you want to work them into your regular monthly payments instead of paying in a lump sum.
