Mortgage Refinance: When It Makes Sense and What It Costs
When refinancing a mortgage pays off, from lowering your rate to dropping PMI, plus cash-out refinancing, closing costs and prepayment penalties.
In the simplest terms, when you refinance a mortgage you’re restructuring a loan with a new, better mortgage rate and term of repayment. In essence, you’re changing the way you pay for your mortgage.
But it’s not as simple as moving from a higher interest rate to a lower one; there can be significant costs associated with refinancing. In addition, it might not always be the best financial move. The decision whether to refinance a mortgage depends on each homeowner’s specific financial situation.
Why should you consider a mortgage refinance?
Generally, if you plan to stay in your home for a while and have a long-term loan, refinancing can be an attractive prospect. Refinancing a mortgage makes sense under certain circumstances:
- Refinance for a lower interest rate
Lowering your mortgage interest rate can lower your monthly payment if the repayment term (duration) remains the same. However, keep in mind that a refinance can carry closing costs of roughly 2% to 5% of the loan balance.
Using a mortgage refinance calculator can help you determine your monthly and lifetime savings, as well as estimate the break-even point — when your savings will start to exceed the costs of the refinance.
Mortgage refinancing for a lower rate can make a lot of sense, especially if your credit score has improved. For example: You had a credit score in the “fair” range, say around 640-659, when you got your mortgage, but you’ve made all of your payments on time and your credit score has improved to 750 or higher. You might qualify for a significantly lower mortgage rate today, if interest rates haven’t risen much since your first mortgage closing. With the average 30-year fixed rate near 7.3% in October 2026, a refinance for a lower rate only pays off if your current rate is meaningfully higher.
You might want to check your credit score and history before you go any further.
- Refinance to switch from an adjustable-rate mortgage to a fixed rate
An adjustable-rate mortgage typically comes with an initial period of a steady interest rate, and then resets to a floating rate for the rest of the loan. This is different from fixed-rate mortgages, which have the same interest rate for the entire loan.
For example, with a 5/1 ARM, the loan’s interest rate would remain the same for the first five years and adjust annually after that. If you keep the ARM after that initial rate period ends and interest rates rise, your payments could jump.
Converting to a fixed mortgage from an ARM can be a wise financial decision, especially if you plan to stay in your home long-term. For example, if you have a 5/1 ARM, you could complete a refinance by the end of the fifth year and lock in a steady rate with a 30-year fixed-rate mortgage.
There are times when choosing or sticking with an ARM makes sense. The interest rate during the fixed-rate period is typically much lower than other mortgages. An ARM could also work if you plan on living in your home for only a short period of time, or if you sell the home before the fixed-rate period ends.
- Refinance to get rid of private mortgage insurance (opens in a new tab)
Whenever you buy a home with less than 20% down, you typically are required to pay private mortgage insurance, which helps to protect the lender in case you default on the loan.
PMI can be quite expensive; annual premiums can cost between 0.5% and 1.5% of the mortgage. For example, a $200,000 loan with 1% mortgage insurance premiums would cost the homeowner $2,000 a year, or $166.66 per month.
Sometimes, homeowners are able to cancel mortgage insurance. By law, you can request cancellation once the balance on the mortgage falls to 80% of the home’s original value, and the insurance must end automatically when the balance is scheduled to reach 78%. However, loans insured by the Federal Housing Administration (FHA) (opens in a new tab) require mortgage insurance for the first 11 years if you put down at least 10%, and for the entire life of the loan if you put down less.
If your loan doesn’t allow you to cancel, you may still be able to get rid of PMI once you have 20% equity in your home by doing a mortgage refinance. You still should go over all the costs of refinancing to make sure the savings outweigh the costs.
Traditional versus cash-out refinance
There are two types of refinances. One is a regular refinance, where the interest rate and repayment term of the loan changes. The other is called a cash-out refinancing (opens in a new tab).
With a cash-out refinancing you are given a new loan, which is larger than the balance remaining on your mortgage. The extra money is paid directly to you. Since the lender in this situation is taking on a higher risk, interest rates will typically be higher than a standard mortgage refinance.
Although a cash-out refinancing may be a tempting way to consolidate credit card debts and other higher-interest loans at the lower interest rate on a mortgage, the consequences of defaulting on your mortgage are far worse than defaulting on credit card payments: You could lose your home. And stretching out payment of your consumer debt over 15 to 30 years is not a wealth-building strategy.
The costs of refinancing your mortgage
Since you’re considering refinancing, you’ve been through a mortgage procedure before. Refinancing your loan will be much the same as applying for the original loan. There will be closing costs to pay, and they may even be higher than the fees you paid the first time around, especially if the value of your home has risen or your creditworthiness has changed for the worse.
Also, you may be getting a discount on property taxes if your home hasn’t been assessed for a while; refinancing may trigger a new assessment, which might increase your tax bill.
Some loans also have prepayment penalties (opens in a new tab): If you repay your loan ahead of schedule, you might have to pay an additional charge. Federal rules limit these penalties: they can last no more than three years and are allowed only on certain fixed-rate qualified mortgages. If you have such a clause in your home loan, watch out for these fine-print charges that might cost you a significant chunk of money, and consider waiting until the prepayment period ends before refinancing.
The bottom line
Refinancing a mortgage takes a lot of time and serious consideration. Just because you see a lower interest rate doesn’t necessarily mean that you should grab it.
Rather than simply focusing on reducing your monthly payment, it’s wiser to refinance when you can save money with a lower interest rate, without extending the payoff term.
