The Housing Rule Everyone Quotes — and Why It Doesn't Work in 2026
There are certain hard-and-fast rules related to housing, like not painting a house bright blue if you want to sell it anytime soon. Another commonly cited rule — arguably the most popular, at least according to financial experts, influencers and mortgage lenders — is the 30% rule. That is, you shouldn’t spend more than 30% of your gross income on housing costs, including mortgage or rent, taxes and insurance.

If browsing local housing listings or even listening to friends lament their insurance fees has you questioning this common wisdom, you’re on to something. This oft-quoted housing rule simply doesn’t hold up in 2026. MoneyLion wanted to understand why.
Housing Prices Have Been on the Rise
For many prospective homebuyers, the math behind the 30% rule hasn’t been working for a while. And they don’t just have gut feelings to go on — there’s data to back it up.
In its 2025 State of the Nation’s Housing report, the Harvard Joint Center for Housing Studies found that the median home price in 2024 was $412,500 — a roughly 60% increase since 2019. The report also found that monthly housing payments rose from $1,445 in 2021 to $2,570 in 2024.
Things hadn’t improved much heading into 2026. When Realtor.com tackled the question of whether the 30% rule remained viable for contemporary homebuyers, writer Hannah Jones referred to home prices and mortgage rates as “stubbornly high.”
She had good reason, given what a 2025 Realtor.com Affordability Report revealed: Among the 50 largest U.S. metro areas, only three were affordable for people with a median income — all three in the Midwest. If you can’t move to one of those areas, sticking to the 30% rule may be nearly impossible.
That same report found even more sobering data: To afford a median-priced home as of May 2025, the typical American household would need to spend about 44.6% of its income on housing — well above the recommended threshold.
Housing Prices Have Outpaced Wages
There are many complex reasons housing has become so cost-prohibitive for American families. However, experts believe wage stagnation is one major factor in why the 30% rule is becoming obsolete.
Jones describes two levels of home affordability: one being housing costs, the other wages.
“Rapid, significant wage growth could make homeownership more affordable, all else being equal. However, the required rate of wage growth is well above historic norms,” she wrote. “Further, wage growth of that magnitude is unlikely to keep all else equal, and would likely boost housing demand, creating conditions that would push home prices and homebuying costs higher.”
The Harvard Joint Center for Housing Studies also raised concerns about stunted wage growth and housing affordability in its State of the Nation’s Housing report. It found that the price-to-income ratio reached 5.0 in 2024 — up from 4.1 in 2019 and far above the 3.2 typical of the 1990s.
In plainer terms, homes now cost far more relative to wages than they did in previous decades. The same 30% rule that may have worked for your parents or grandparents just doesn’t hold water in today’s economic reality.
There’s a Geography Problem, Too
Trends like these prompted writer Mary K. Jacob of The New York Post to quip, “Homeownership is about to cost an arm, a leg — and a second salary.”
She was responding to an analysis that used housing data from Redfin to predict what the next decade in housing could look like, including 2026 and beyond. That data painted a bleak picture for anyone assuming that moving to a less densely populated area might make the 30% rule feasible.
To illustrate how outdated the rule has become, Jacob pointed to Montana — long considered a bastion of affordability for middle- and working-class families.
“Nowhere is the affordability crunch more severe than in Montana, where home prices are forecast to hit roughly $932,584,” she wrote. “Once considered a haven of affordable living, the state’s housing market has spiraled upward amid a pandemic-fueled influx of remote workers.”
And if the math is already strained in states like Montana, applying the 30% rule in high-cost markets such as California or New York becomes even less realistic.
The Bottom Line
We know this can feel like a lot of doom and gloom. But just because the 30% rule is outdated in 2026 doesn’t mean homeownership is off the table.
Instead, it means buyers need a more flexible, personalized approach — one that accounts for today’s housing costs, local markets and broader financial goals. With patience, strategy and guidance from a financial expert aligned with your path to homeownership, finding a home you can truly afford is still possible.
