Refinancing your mortgage means replacing your existing home loan with a new one — typically to get a lower interest rate, reduce your monthly payment, shorten your loan term, or access equity. It’s one of the most impactful financial moves a homeowner can make, but it only makes sense under the right conditions. Here’s how to evaluate it.
The two main types of refinancing
- Rate-and-term refinance. You replace your current mortgage with a new one at a different interest rate, loan term, or both. No cash is taken out. The goal is usually a lower rate, lower payment, or shorter payoff timeline. This is the most common type of refinance.
- Cash-out refinance. You take out a new mortgage for more than you owe, and receive the difference as cash. For example, if you owe $200,000 and your home is worth $350,000, you might refinance for $260,000 and receive $60,000 in cash. The trade-off: higher loan balance and potentially higher monthly payments. Used to fund renovations, consolidate debt, or make investments.
The break-even calculation
Refinancing costs money — closing costs typically run 2–5% of the loan amount, or $4,000–$10,000 on a $200,000 loan. To determine whether a refinance makes sense, calculate your break-even point: divide the total closing costs by your monthly savings. If closing costs are $6,000 and your new payment is $150/month lower, your break-even is 40 months (about 3.3 years). If you plan to stay in the home longer than that, the refinance saves you money. If you plan to sell sooner, you’ll pay more in closing costs than you’ll save in payments.
When refinancing makes sense
- Rates have dropped significantly since you bought. The traditional rule of thumb is that a refinance makes sense if you can reduce your rate by at least 1%. While this isn’t a hard rule, it’s a useful starting point — smaller rate reductions have smaller monthly savings and longer break-even periods.
- You want to shorten your loan term. Refinancing from a 30-year to a 15-year mortgage typically comes with a lower rate and much less total interest paid, though monthly payments are higher. If your income has increased since you bought, this can be a smart move.
- You want to remove PMI. If your home has appreciated and you now have 20%+ equity, refinancing into a new conventional loan eliminates PMI — especially valuable if you have an FHA loan with lifetime MIP.
- You want to switch from an ARM to a fixed rate. If you have an adjustable-rate mortgage and rates are rising or you want payment certainty, refinancing to a fixed rate locks in predictability.
The refinancing process step by step
Start by checking your current rate and remaining balance on your mortgage statement, then get quotes from at least 3 lenders — your current servicer, a major bank, and a mortgage broker or online lender like Better or Rocket Mortgage. Compare the APR (which includes fees) rather than just the interest rate. Once you choose a lender, the process mirrors the original mortgage application: you’ll submit income documents, get an appraisal, go through underwriting, and close. The typical timeline is 30–45 days. You’ll pay closing costs at close, either out of pocket or rolled into the new loan balance.
No-closing-cost refinances
Some lenders offer “no-closing-cost” refinances where closing costs are either rolled into the loan balance or covered through a slightly higher interest rate. These can make sense if you have limited cash on hand or plan to sell or refinance again within a few years — but over a long hold period, you typically pay more than you would with upfront closing costs. Run both scenarios and compare total interest paid over your expected hold period.
What to watch out for
Resetting your loan term is the most overlooked cost of refinancing. If you’re 7 years into a 30-year mortgage and refinance into a new 30-year loan, you’ve just added 7 years back to your payoff timeline — even if your monthly payment drops. To avoid this, consider refinancing into a shorter term (20 or 15 years) or making extra principal payments on the new loan. Also watch for prepayment penalties on your current mortgage — uncommon on modern loans but worth verifying before you proceed.
