Key Takeaways
- The typical U.S. mortgage holder pays $1,332 a month in principal and interest at a rate of about 4.0%, but buying the median-priced home at 7.32% would cost an estimated $2,468 a month, an 85.3% jump of about $1,100.
- Portland, Maine, faces the steepest jump in the country at 167.0%, ahead of San Jose at 164.8% and Los Angeles at 161.9%, while Pittsburgh has the smallest gap at 43.3%.
- Rates would need to fall to about 6.0% for half of U.S. households to afford the median-priced home, and even then the typical payment would still run 61.7% higher than what current mortgage holders pay.
Most homeowners who might like to move are doing the math and staying put. A Realtor.com report released on November 11, 2026, puts a hard number on why: the typical mortgage holder would need about $1,100 more each month in principal and interest to buy a median-priced home today.
The report compares what current mortgage holders actually pay with what buying now would cost. The typical outstanding mortgage carries a rate of about 4.0%, while the estimate for buying uses a rate of 7.32%, the October 22 rate, on the September 2026 median-priced home of $419,250 with a typical down payment of 14.3%.
The Move-Up Math: $1,332 a Month Becomes $2,468
The gap is not a rounding error. It is the difference between a loan written in a cheap-money era and a loan written today, on a home that also costs more than it did when most current loans were made.
| Measure | Figure |
|---|---|
| Typical current mortgage holder payment (principal and interest) | $1,332 a month |
| Typical rate on an outstanding mortgage | 4.0% |
| Estimated payment to buy the median-priced home at 7.32% | $2,468 a month |
| Payment increase to move | 85.3%, about $1,100 a month |
| Added share of household income spent on housing | 15.6 percentage points |
| September 2026 median-priced home used in the estimate | $419,250, with a 14.3% down payment |
In roughly one-third of the 100 largest metros, buying a median-priced home would more than double the typical mortgage holder’s current monthly principal-and-interest payment. The widest gaps sit in high-priced markets where existing loans carry especially low rates.
| Most locked-in metro | Current payment | Estimated payment to buy | Gap |
|---|---|---|---|
| Portland-South Portland, ME | $1,270 | $3,392 | 167.0% |
| San Jose-Sunnyvale-Santa Clara, CA | $2,659 | $7,039 | 164.8% |
| Los Angeles-Long Beach-Anaheim, CA | $2,149 | $5,628 | 161.9% |
| Oxnard-Thousand Oaks-Ventura, CA | $2,140 | $5,261 | 145.9% |
| Albany-Schenectady-Troy, NY | $1,024 | $2,458 | 140.2% |
San Jose shows why a big down payment does not solve the problem. Its estimated payment assumes a typical down payment of 26.2%, and the payment to buy still reaches $7,039 a month.
“Home sales have been stuck for several years, and this research helps illuminate one of the major friction points for today’s homeowners who might like to move. Together, home prices and mortgage rates have drastically changed what it takes to buy a home,” said Danielle Hale, chief economist at Realtor.com.
“For the typical mortgage holder, buying a home at today’s median-price and current rates would mean finding about $1,100 more each month for principal and interest, before property taxes and insurance. Lower rates would help, but even at 6%, the typical payment would still be more than 60% higher. For many families, that is money they simply don’t have to spare,” Hale said.
The lock-in sits on top of a mortgage stock that is already historically large. As covered in our report on mortgage balances reaching $13.4 trillion in the third quarter, households are carrying record mortgage debt, much of it written at rates far below anything a new buyer can get today.
The Market Is Unlocking, but at a Pace Measured in Years
The loans holding the market in place were mostly written in two extraordinary years. Roughly 27% of the most recent fixed-rate mortgages on record for single-family homes and condominiums were originated in 2020 and 2021 alone, and about two-thirds of them were refinances.
Once rates rose in 2022, activity collapsed. In the four and a half years between 2022 and the most recent data in July 2026, only about one in four mortgages on record (25.3%) was originated, and in the 12 months ending July 2026 just 4.3 million mortgages were originated, only 6.6% of all mortgages on record.
- Just 22.5% of outstanding mortgages carry a rate of 6% or higher, according to the FHFA data cited in the report.
- More than 40% (42.8%) of outstanding mortgages have a tenure of 5 to 7 years, tracing back to roughly mid-2019 through mid-2022.
- The share of outstanding mortgages with a rate below 6% slipped from 79.8% to 77.5% over the past year, and the share below 3% edged down from 20.2% to 19.2%.
- Nearly one in four mortgages in the West carries a rate below 3%, compared with 19.2% nationally, and 82.3% of outstanding mortgages in the West sit below 6%.
That slow turnover is why existing-home sales have hovered near 4 million a year since 2023, close to multi-decade lows. The report notes that most sales now come from need-to-move situations such as marriage, divorce, a growing family, or a new job.
The cheapest markets tell a different story, and it is the most useful one in the report for investors. Where home prices are low and existing loans already carry higher rates, the penalty for moving is far smaller, so homes keep changing hands.
| Least locked-in metro | Current payment | Estimated payment to buy | Gap |
|---|---|---|---|
| Pittsburgh, PA | $1,005 | $1,441 | 43.3% |
| Baltimore-Columbia-Towson, MD | $1,522 | $2,208 | 45.0% |
| Buffalo-Cheektowaga, NY | $1,060 | $1,549 | 46.1% |
| New Orleans-Metairie, LA | $1,119 | $1,719 | 53.6% |
| San Antonio-New Braunfels, TX | $1,277 | $2,053 | 60.8% |
“More affordable markets offer homeowners a smaller payment jump, not an escape from higher costs,” said Hannah Jones, senior economist at Realtor.com. “The estimated increase is about 43% in Pittsburgh versus 165% in San Jose. Lower home prices and, in many markets, higher rates on existing loans help narrow that gap, making a move more attainable.”
San Antonio shows a second way the gap closes: falling prices. Its median listing price was $320,374 in September, down 2.9% from a year earlier and 16.2% below its mid-2022 peak, and prices there have fallen year over year for more than three years.
Roughly 75% of mortgages carry a rate below 6% in the South and Midwest, compared with 78% nationally. Because more owners in those regions already hold higher-rate loans, each move resets a borrower to a current rate, which keeps transaction activity steadier.
Buyers are already hunting for ways around the rate wall, including adjustable-rate loans, as our coverage of ARMs reaching a record 17% of mortgage locks in October showed. The locked-in report explains the other half of that picture: the sellers those buyers need are the ones facing the 85.3% jump.
What Rate Would Actually Unlock the Market?
The report models the payment at lower rates, and the answer is sobering. Each half-percentage-point decline in the mortgage rate lowers the estimated monthly payment by roughly $110 to $120 and trims the gap with current mortgage holders’ payments by about 8 to 9 percentage points.
| Mortgage rate | Estimated monthly payment | Gap vs. typical current payment | Share of households who can afford the median-priced home |
|---|---|---|---|
| 7.32% | $2,468 | 85.3% | 44.5% |
| 7.0% | $2,390 | 79.5% | 45.8% |
| 6.5% | $2,271 | 70.5% | 48.0% |
| 6.0% | $2,154 | 61.7% | 50.2% |
| 5.5% | $2,040 | 53.2% | 52.5% |
| 5.0% | $1,929 | 44.8% | 54.8% |
Here is the fresh insight most coverage will miss: even a return to the roughly 4.0% rate on the typical outstanding mortgage would leave the payment about 29% higher than what the typical current mortgage holder pays, because home prices have risen since most of these loans were originated. Rate cuts alone cannot hand owners back their old payment.
“Lower rates alone would not erase the affordability gap,” said Jones. “Slower home-price growth and rising incomes would also help narrow the difference between what households pay now and what it would take to buy.”
The report expects the thaw to stay gradual. With 30-year rates above 7%, nearly every new mortgage over the next year will likely land in the 6%-or-higher bucket, which Realtor.com estimates would lift that share from 22.5% to roughly 27% to 28.5% by mid-2027, the highest in more than a decade.
For beginner investors, the actionable playbook from this report is specific:
- Shop where the gap is smallest. Pittsburgh, Baltimore, Buffalo, New Orleans, and San Antonio combine lower prices with owners who face a 43% to 61% payment jump instead of 140% or more, so listings turn over and motivated sellers actually exist.
- Run your own move-up math before listing anything. Use the scenario table above: at 6.5% the typical payment is still $2,271, so price a planned purchase off the rate you can get, not the rate you hope for.
- Do not wait for a single rate drop to flood the market with listings. A half-point drop trims only about $110 to $120 a month, so build your buy box around today’s payment reality, the same discipline behind strategies like using a VA loan’s lower rate and zero down payment to buy years sooner.
- Watch the 6% line. That is the rate at which half of households could afford the median-priced home, and the point where sidelined sellers start to become listings.
