Refinancing your mortgage can help lower your monthly payments and save you money over the life of the loan, but doing so more than once (or many times) could cost you more than you expect.

Here’s what you need to know about how often you can refinance your mortgage — and what multiple refinances might involve.

How often can you refinance your home loan?

There is no limit to how many times you’re allowed to refinance your mortgage, though a lender might enforce a waiting period between when you close on a loan and refinance to a new one.

How soon can you refinance a mortgage?

Often, lenders have what’s called a “seasoning” requirement — a period of time you need to wait before refinancing, generally at least six months.

However, that might only apply if you’re refinancing with your current lender; you could find a new financial institution that is willing to do the refinance sooner and skirt the six-month rule altogether. One exception: With a cash-out refinance, the waiting period  is usually firm at half a year.

These rules apply primarily to conventional loans — that is, mortgages issued and backed by a private lender. For government-insured mortgages, there are different requirements:

  • FHA streamline refinance: Borrowers who have an FHA loan and are looking to do an FHA streamline refinance are required to wait 210 days (seven months) from the closing date of the first mortgage, and six months from the due date of their first mortgage payment, before being able to refinance.
  • FHA cash-out refinance: Borrowers taking cash out during an FHA refinance have only the six-months-from-their-first-payment requirement.
  • VA streamline refinance:  Borrowers with a VA loan considering a VA streamline refinance (officially called an Interest Rate Reduction Refinance Loan, or IRRRL) are required to wait either 210 days from the date of their first mortgage payment or the date the sixth mortgage payment is made, whichever is later.
  • VA cash-out refinance: Borrowers taking cash out during a VA loan refinance must wait 210 days from the closing date of the first mortgage.

Aside from these timelines, when considering how often you can refinance a mortgage, you want to make sure doing so makes financial sense. If the new interest rate isn’t significantly better than what you have right now, you might not save much after factoring in the cost of the refinance.

Cost of refinancing multiple times

It doesn’t always make sense to keep refinancing your home simply because interest rates go down or your credit score goes up. Like your first mortgage, a refinance has closing costs.

Each time you refinance, you’ll have to pay fees, such as for the application, appraisal, credit check, attorney and title search. These can vary depending on your area and the lender, though it’s common to pay anywhere from 2 percent to 5 percent of the loan principal.

The key to realizing savings is to take into account how much you’re lowering your interest rate, and how long you intend to stay in the home. If you plan to live there long-term, refinancing more than once could make sense, but you have to factor in your closing costs carefully — and how they influence your break-even point.

Using a refinance cost calculator can help you figure out how long you’d need to stay in the home to come out ahead financially by refinancing.

Example: Calculating the cost of additional refinances

Let’s say you have a 30-year fixed mortgage for $240,000 with 5.71 percent interest. Your monthly mortgage payment is $1,394, excluding insurance and taxes.

Fifteen years into your term, your balance is now $168,498. Rates have fallen, so you decide to refinance to 3.7 percent and a 15-year loan, cutting your monthly mortgage payment to $1,221 and dropping $31,108 in interest.

If the closing costs equal 3 percent of the principal, or $5,055, you’d break even in roughly two years. However, if you’re charged 5 percent of the principal ($8,425), it’d be four years before you recouped them.

Loan principal Refinance term Closing costs Break-even
$168,498 15 years 3% ($5,055) 2.4 years
$168,498 15 years 5% ($8,425) 4.1 years

What if after six months you decide to refinance a second time? Your balance is now $164,902. Suppose you can lower your rate to 3.19 percent and extend the loan 15 years. You’d bring down your monthly mortgage payment to $1,154. If closing costs remain the same (3 percent of the principal, or $4,947), it’d be six years to recoup them. If your closing costs were 5 percent ($8,245), it’d be 10 years.

Loan principal Refinance term Closing costs Break-even
$164,902 15 years 3% ($4,947) 6.1 years
$164,902 15 years 5% ($8,245) 10.2 years

Now, what if when you refinance the second time, you get a lower rate, but only slightly? If you refinance from 3.7 percent to 3.68 percent, for instance, now into a 30-year loan to lower your payment (at 15 years, you’d have a higher payment), you’d break even on closing costs in less than a year, and have a lower payment ($757), but you’d also end up with higher interest in total — more than $60,000.

Loan principal Refinance term Interest rate Interest savings Closing costs Break-even
$164,902 15 years 3.68% -$60,121 3% ($4,947) 10.6 months

As you can see, it’s crucial to calculate the impact of closing costs, your new rate and how long you plan to live in the home to ensure that refinancing once, two times or even more than that is worth it.

Important considerations before refinancing again

You’ll have to pay closing costs

New day, new loan, new set of closing costs. And guess what? They’re not getting cheaper.

The average refinance closing costs were $2,375 in 2021, according to ClosingCorp — up $88, or 3.8%, from 2020. In general, you can expect to pay anywhere from 2 percent to 5 percent of the loan principal in these fees.

Keep this expense in mind, particularly if you plan not to pay it upfront, but to roll it into your mortgage balance. That’s less of an upfront bite, but you’ll be increasing the overall amount owed on your mortgage (and its interest) with each subsequent refinance.

You’ll have to qualify again

If your credit or financial picture has changed (and not in a good way) since you last applied for a refinance or mortgage, it could hold you back from qualifying for an additional refinance, or shut you out of the lowest possible rate, which could negate any potential savings.

You could face a prepayment penalty

Although it’s uncommon, you might also incur a prepayment penalty, or a fee you’re charged if you pay the loan before the term is up, which can add to your costs. Make sure to read the fine print of your loan to see if there is a penalty, and, if so, consider whether paying it is worth it in the long run.

Should you refinance your mortgage more than once?

Refinancing your mortgage can offer some significant advantages. Here are a few scenarios when it could make sense for your financial situation:

  • Interest rates have dropped a lot. The general rule of thumb is to look for refinance rates that are a minimum of 1 percentage point lower than your current one, or even more depending on your closing costs.
  • Your credit score has improved significantly. If your credit score is much higher than it was when you got your first mortgage, you might qualify for lower rates now, helping you save.
  • You need some cash. If you could use some ready money to complete home renovations, consolidate debt or for a large expense, a cash-out refinance could be worthwhile, although you’ll have pay a higher interest rate (than for the usual rate-and-term refinance).
  • You’re having trouble keeping up with current payments. If you need some breathing room, refinancing can make sense, especially if you qualify for a lower rate. Even if you don’t, a new, longer loan term can mean smaller monthly payments. However, note that each time you lengthen your loan term, you may end up paying more in interest overall.
  • You can eliminate private mortgage insurance. If you have enough equity in your home, a refinance can provide the opportunity to remove private mortgage insurance (PMI). With the cost of PMI amounting to between $30 to $70 per month for every $100,000 borrowed, eliminating this expense can present significant savings.

Bottom line

Now that you know how often you can refinance your home, you’ll want to do some careful research to see whether it’s worth it to do it multiple times. The costs do add up, and it’s a time-consuming process.

So you don’t want to make a habit of it. Still, you might have to go for it if the right circumstances present themselves. If you qualify for a rate that’s much lower than what you have now, you can save thousands in interest. If it avoids you getting delinquent or defaulting on your mortgage, refinancing can be a smart move too. No matter your reason, shop around with multiple lenders to find the best rates and terms.
