When does refinancing make sense?

Short answer

Refinancing makes sense when you will keep the new loan longer than its break-even point: total closing costs divided by your monthly savings. If a refinance costs $6,000 and cuts your payment by $250, break-even is 24 months, so it makes sense if you plan to stay at least two years and does not if you plan to sell next spring. Rates vary daily and we never quote them on this page; the method below works at any rate, and it also covers when a cash-out refinance beats a HELOC and when it does not.

The break-even formula

Break-even months = total refinance costs / monthly savings.

Count every cost: lender fees, appraisal, title, recording, and Florida's taxes on the new loan (documentary stamps of $0.35 per $100 on the note and intangible tax of $2 per $1,000 on the mortgage). On a $400,000 refinance those two taxes alone are $1,400 and $800. Do not count prepaid interest or the escrow deposit as costs; you get the old escrow balance refunded and you would pay interest either way.

Count only true savings: the difference in principal and interest. If you also reset a 25-year remaining term to 30 years, part of the lower payment is just stretching the loan, not saving money. To compare fairly, look at what you would pay on the new loan over the same remaining term, or compare total interest.

Example: $400,000 balance, 25 years left. New loan costs $7,000 all in. New payment is $280 lower. Break-even = $7,000 / $280 = 25 months. Keep the house more than about two years and the refinance pays off; sell or refinance again sooner and it does not.

Rate-and-term vs. cash-out

A rate-and-term refinance (Fannie Mae calls it a limited cash-out refinance) replaces your loan with a new one for about the same balance, to lower the rate, shorten the term, drop mortgage insurance, or move from an adjustable to a fixed rate. Fannie Mae allows up to 97% LTV on a primary residence for a fixed-rate limited cash-out refinance, and FHA allows up to 97.75%. Pricing is the same as or close to purchase pricing.

A cash-out refinance replaces your loan with a bigger one and gives you the difference in cash. Fannie Mae caps it at 80% LTV on a 1-unit primary residence, 75% on a second home or investment property. Cash-out loans carry higher pricing adjustments than rate-and-term, and you pay Florida's note stamps and intangible tax on the entire new balance, not just the cash you take.

Common reasons a refinance makes sense even without a lower rate: removing FHA mortgage insurance once you have 20% equity by switching to conventional, removing a co-borrower after a divorce, or paying off a HELOC that has reset to a high variable rate. See refinance, FHA streamline, and VA IRRRL for the low-document options.

HELOC vs. cash-out refinance

If you need cash from your equity, the real question is whether to touch your first mortgage at all.

• Keep your first mortgage and add a HELOC or a fixed second mortgage when your current first-mortgage rate is lower than today's rates. Refinancing a $400,000 loan to pull $60,000 would reprice the whole $460,000 at today's rate; a second lien reprices only the $60,000. A HELOC is variable-rate with a draw period and then a repayment period; a fixed second has one rate and one payment. Florida's note stamps and intangible tax apply only to the second-lien amount.
• Cash-out refinance when your current rate is at or above today's rates, when you want one payment, or when the second-lien rate offered is far higher than a new first mortgage. It can also make sense when you need more cash than second-lien lenders will extend; cash-out goes to 80% LTV on a primary residence under Fannie Mae, and some second-lien lenders stop lower.

Run both as total monthly cost and total interest over the time you expect to keep the house. We quote the three options on one page so the trade-off is visible.

Four situations where refinancing usually does not make sense

• You plan to move before break-even. If the math says 30 months and you expect to sell in 18, keep your loan.
• You have a low fixed rate and just need cash. A second lien usually wins; see above.
• You are late in the loan. In the last third of a 30-year loan most of your payment is principal. Restarting at 30 years can cost far more in total interest even at a lower rate, unless you shorten the new term.
• You have a Hometown Heroes or other deferred second mortgage. Refinancing the first makes the second due in full. Add that payoff to your costs; see our Hometown Heroes guide.

Also watch the fine print: a 'no closing cost' refinance means the costs are paid through a higher rate or added to the balance. Neither is free; both change the break-even. Your Loan Estimate shows the real numbers.
