6 Things to Know Before You Refinance Your Mortgage

By Erica Coleman · July 10, 2026

Here’s the number nobody mentions in the rate-drop headlines: closing costs on a refinance typically run 2% to 6% of your loan amount. On a $300,000 mortgage, that’s $6,000 to $18,000 due before you save a single dollar.

Refinancing can genuinely put money back in your pocket. It can also cost you money if you do it at the wrong time, for the wrong reason, or without doing the math first. About 21% of mortgaged homeowners are currently carrying a loan at 6% or higher, according to the Federal Housing Finance Agency, which means a real slice of the country has a legitimate reason to look at refinancing right now. Here’s what to check before you do.

Calculate your break-even point first. This is the single most important number in the entire decision. Take your total closing costs and divide by your monthly savings — the result tells you how many months it takes before the refinance actually starts saving you money. If your closing costs are $6,000 and you save $200 a month, you break even in 30 months. Stay in the home longer than that, and you come out ahead. Sell or refinance again before then, and you’ve lost money on the transaction. The Federal Reserve’s consumer guide walks through this exact math and is worth five minutes before you talk to a single lender.

Know why you’re actually doing it. A lower rate is the obvious reason, but it isn’t the only one. Removing private mortgage insurance once you’ve built enough equity, switching from an adjustable-rate mortgage to a fixed one before a scheduled rate reset, or shortening your loan term to pay off the house faster are all legitimate reasons to refinance even if the headline rate improvement looks modest.

Don’t refinance if you’re moving soon. If you’re planning to sell within the next three to five years, the math rarely works. You’ll pay thousands in closing costs and likely move before you hit your break-even point. This is the mistake homeowners make most often — chasing a lower rate without asking whether they’ll actually be in the house long enough to benefit from it.

Shop more than one lender. Rates and fees vary meaningfully between lenders, and accepting the first offer that lands in your inbox is one of the most expensive mistakes a homeowner can make. Compare the Annual Percentage Rate, not just the advertised interest rate — the APR folds in origination fees and points, so it reflects what the loan actually costs you.

Understand what resetting your loan term really means. Refinancing into a new 30-year loan resets your amortization schedule back to year one, which means the first several years of payments go mostly toward interest again, not principal. Even if your monthly payment drops, you could end up paying more total interest over the life of the new loan than you would have by just keeping your original mortgage.

Watch what happens if you roll closing costs into the loan. Many homeowners choose this option to avoid paying cash at closing, but it means financing those costs — appraisal fees, title work, origination charges — for the next 15 to 30 years, with interest. An $6,000 closing cost bill rolled into a new 30-year loan can end up costing considerably more than that over time.

None of this means refinancing is a bad idea. For a lot of homeowners locked into a rate from 2022 or 2023, when 30-year rates peaked well above 7%, today’s environment is a genuine opportunity. The difference between a smart refinance and an expensive mistake almost always comes down to the same thing: whether someone actually ran the numbers before they signed anything.
