Frequently Asked Questions
Complete indexable directory of answers (8 questions)
How do I know if I should refinance my mortgage?
Use our mortgage refinance calculator to compare your current loan with a new rate. If your monthly savings exceed the closing costs within a reasonable timeframe (typically 2-3 years), refinancing may be worthwhile.
Is it worth refinancing for a 1% lower interest rate?
Often yes, but the key is how long you plan to stay in the home. If your monthly savings are $150 and closing costs are $3,000, you must stay at least 20 months just to break even.
What is a "no-closing-cost" refinance?
Lenders roll the closing costs into the loan balance or increase the interest rate to cover them. While you pay nothing upfront, your monthly payment and total lifetime costs will be higher.
How much does it cost to refinance a mortgage?
Refinance closing costs typically range from 2% to 5% of the loan balance. This includes lender fees, appraisal, title insurance, and recording fees. Our refinance calculator with closing costs helps you estimate these expenses.
Should I refinance to a shorter loan term?
Refinancing from a 30-year to a 15-year mortgage typically offers lower interest rates but higher monthly payments. The total interest savings can be substantial — often hundreds of thousands of dollars over the life of the loan.
