Frequently asked questions
- When does refinancing make sense?
- When your monthly savings recover the closing costs before you sell or move — that's the break-even point — and ideally with a meaningfully lower rate.
- What are typical closing costs?
- Refinance closing costs often run 2–5% of the loan amount, covering appraisal, origination, and title fees.
