How a 50-year mortgage would affect homeowners in each state

How a 50-year mortgage compares with a 30-year mortgage

Before digging into the details of how a 50-year mortgage could impact homebuyers in each state, it’s worth taking a moment to understand where this proposal came from and why some people are drawn to it. The answer lies in the current housing affordability crisis, in which many homeowners are “house-poor” (heavily burdened by housing costs) and homeownership has been pushed out of reach for many others.

“The real problem today is not just the nominal interest rate,” said Josip Rupena, CEO of Milo, a fintech company that specializes in mortgages for cryptocurrency investors. “It is that the monthly payment, relative to incomes and home prices, does not feel affordable or worth it to many buyers.”

The primary draw of a longer mortgage term is lower monthly payments, which can make homeownership more accessible by lowering income qualifications for prospective buyers.

“If you can't afford $2,500 a month on a 30-year mortgage, perhaps you can afford $2,000 a month on a 50-year term,” explained Reza Sardeha, founder of the digital homebuying platform Anyone.

Drawbacks of the 50-year mortgage

Unfortunately, extending a mortgage term length from 30 to 50 years isn’t a silver bullet to solve the affordability crisis. It decreases the monthly payment, but not as dramatically as people may imagine.

Nationwide, a 50-year mortgage would lower monthly payments (principal and interest only) from a 30-year loan by about $228, bringing the typical monthly payment to $1,759. However, a longer loan term would increase the total interest owed by more than $340,000, nearly as much as the median U.S. home value.

“A lot of real estate experts feel like this would basically be like glorified renting, and I don’t think that’s too far off,” said Harrison Stevens, vice president of marketing at TurboTenant, which provides software to rental property managers.

Beyond dollars and cents, there’s also the sobering question: Will you live long enough to make your final payment? The median age of a first-time homebuyer is now 40 years old, an all-time high, according to the National Association of Realtors. Five decades from now, think about how old you’ll be, and whether you’ll be willing or able to make that monthly mortgage payment.

“You may not be alive by the end of that time period, so the financial burden could be passed down to your heirs,” said Adam Hamilton, the co-founder of REI Hub, a rental property software company.

With that in mind, here’s a look at where a 50-year mortgage would cost homebuyers the most. Then, read on for a closer look at the top- and bottom-ranked states.

States where a 50-year mortgage costs the most over time

In these states, homebuyers would be hit the hardest by the increased interest over the life of a 50-year mortgage:

1. Hawaii
2. California
3. Massachusetts
4. Washington
5. Colorado
6. New Jersey
7. Utah
8. Oregon
9. New York
10. New Hampshire

These states have the nation’s highest median home values, ranging from $843,496 in Hawaii to $475,400 in New Hampshire, as well as some of the highest household incomes. Massachusetts tops the list with a median household income of $104,828, while Oregon has the lowest of the bunch, at $85,220 — still above the national median.

In an ideal world, these higher incomes would reflect stronger purchasing power for prospective homebuyers in these states. But the total difference in interest paid over 20 extra years of borrowing in these states is staggering.

In Hawaii, for example, saving more than $500 on your monthly mortgage payment might make a 50-year mortgage seem appealing. But it would cost about $800,000 more in interest than a 30-year loan, with total interest exceeding $1.7 million, more than twice the typical home value in the state, and nearly five times the typical U.S. home value.

Where a 50-year mortgage makes the smallest long-term difference

In the following states, homebuyers wouldn’t be hit as hard by the increase in interest on a 50-year mortgage:

1. West Virginia
2. Mississippi
3. Oklahoma
4. Louisiana
5. Arkansas
6. Kentucky
7. Iowa
8. Ohio
9. Kansas
10. Alabama

These states have the lowest home values in the country, which means many buyers need smaller home loans to cover the cost; the smaller the principal, the less interest is owed over time.

Still, a 50-year mortgage offers minimal short-term relief. Compared with a 30-year loan, the difference in monthly payments is small, ranging from $104 in West Virginia to $146 in Alabama.

To make matters worse, the typical household income in the states above is lower than the national median, which means homeowners here are at a higher risk of being cost-burdened by housing debt.

Take West Virginia, for example. A 50-year loan would lower the typical monthly payment from $908 to $804 — just over $100 — while the difference in total interest between a 30-year and a 50-year loan is $155,520. That’s nearly enough money to buy another home: The median home price in the Mountain State is just 5% higher, at $163,731.

Total interest over the life of the 50-year home loan would be $335,139 — more than twice the typical home value in the state.

Curious what a 50-year mortgage could mean for you? Using the latest home values and interest rates, we forecast what homebuyers in each state could expect to pay in interest on a 30-year and a 50-year mortgage. Below, see how your state ranks, and consider how the 50-year mortgage would impact your short-term wallet and long-term wealth.

How a 50-year mortgage could impact the housing market

Beyond the state-by-state impact, what kind of effect would the 50-year mortgage have on the housing market and the broader economic landscape?

Some experts predict a short-term bubble and a longer-term bust.

“We'll see a temporary boom as more buyers qualify, driving prices higher and ultimately worsening affordability,” said Sardeha. “In 30 to 40 years, when large cohorts of 50-year mortgage holders reach retirement or pass away, we risk market flooding and a delayed but severe correction, especially as the baby boom generation exits the market.”

Unfortunately, extending mortgage terms doesn't address the core issue: Home prices have outpaced wage growth. “What's worse is that artificially inflating purchasing power will prompt sellers to raise prices further, negating any gains,” said Sardeha.

Instead of longer loans, Sardeha points to solutions that tackle affordability at its roots: shared equity mortgages to reduce capital requirements, zoning reform to increase supply, and policies addressing wage stagnation.

“Rather than adding decades to a loan, we should be focusing on smarter underwriting options that reflect how Americans actually earn and manage their income today,” said Marc Halpern, CEO of Foundation Mortgage Corporation in Miami Beach, Florida. “Alternative documentation programs — such as bank statement or 1099 loans — can help qualified borrowers achieve homeownership responsibly, without turning a mortgage into a lifelong obligation.”

Expert insight: How to pick the right mortgage for you

If you’re financially able, is it better to overpay your mortgage each month to try to pay the loan off faster? Put another way, if the 50-year mortgage replaced the 30-year term available today, what could homebuyers do to try to make lemonade out of a rather lemony situation?

“If forced into a 50-year mortgage, treat it like a 30-year through higher payments. This dramatically reduces total interest and builds equity faster,” said Sardeha.

And overpaying isn’t just a good idea for the hypothetical 50-year mortgage; it’s a smart strategy if you have a 30-year mortgage, too.

If you’re choosing between a 30- and a 50-year loan term, “the better option would be to go with a 30-year mortgage and (make) payments every two weeks, instead of once a month,” said Jason Patton, an agent with ARC Realty in Birmingham, Alabama. By paying half your monthly mortgage bill every two weeks, you’d make 13 total payments each year — one more than if you made the standard 12 monthly payments.

With this method, you’d shave a whopping seven years off of a typical 30-year mortgage and build up your equity faster, Patton explained.

The bottom line on the 50-year mortgage

So, what’s the final verdict on the proposed 50-year mortgage? Is it worth it for a first-time homebuyer?

“Any policy that prioritizes access at the expense of financial health risks creating more problems than it solves.”

Ultimately, the notion of the half-century mortgage “may be better hypothetically than in reality,” said Hamilton of REI Hub. “It doesn’t fix any of the root causes of the lack of home affordability right now.”

“Homeownership should be a path to freedom, not a 50-year burden,” added Halpern of Foundation Mortgage. “Any policy that prioritizes access at the expense of financial health risks creating more problems than it solves.”

Methodology

To estimate how a 50-year mortgage could affect homebuyers, we compared the cost of a typical 30-year fixed-rate mortgage with a hypothetical 50-year mortgage at both the national and state levels. We considered the following for this comparison:

• Home values: We used the Zillow Home Value Index (ZHVI), a publicly available dataset that shows median home values across the U.S. We used the most recent data available at the time of analysis (2024).
• Down payment and loan amount: We assumed a 10% down payment. For each state, we calculated the loan amount as 90% of that state’s median home value.
• Mortgage rate: We used the average 30-year fixed mortgage rate (6.26%) from Freddie Mac’s Primary Mortgage Market Survey as of Nov. 20, 2025. We applied the same interest rate to both the 30-year and 50-year scenarios to isolate the impact of the longer loan term. (A hypothetical 50-year mortgage would almost certainly include a higher interest rate than a 30-year mortgage.)

How we calculated costs
For each state, we did the following:

1. Calculated the monthly payment (principal and interest only) on a 30-year mortgage using the loan amount and interest rate.
2. Calculated the monthly payment (principal and interest only) on a 50-year mortgage using the same loan amount and interest rate.
3. Calculated the total amount paid over the life of the loan by multiplying the monthly payment by the number of months.
4. Calculated total interest paid by subtracting the original loan amount from the total amount paid over the life of the loan.
5. Measured the extra cost of a 50-year mortgage by subtracting the total interest paid on a 30-year loan from the total interest paid on a 50-year loan.

Ranking the states
States were ranked by the additional interest a typical buyer would pay on a 50-year mortgage compared with a 30-year mortgage. States with the largest increases in total interest were ranked higher.
