How the K-Shaped divide is reshaping US housing

Key points:

• • First-time buyers are at historic lows as affordability pressures favor equity-rich and investor buyers.
• • Housing costs now far exceed traditional income thresholds, widening generational wealth gaps.
• • Supply constraints and investor competition are deepening regional and economic divides.

February 2026 — In America’s K-shaped housing economy, first-time buyers are getting squeezed out of the market, while high-net worth investors continue to capture a greater portion of transactions and exert more sway over pricing. This divergence is repositioning where capital flows and who accumulates wealth through real estate.

“Unfolding in the housing market is a tale of two cities,” Jessica Lautz, deputy chief economist at the National Association of Realtors (NAR), said in a recent analysis. “We’re seeing buyers with significant housing equity making larger down payments and all-cash offers, while first-time buyers continue to struggle to enter the market.”

According to Lautz, homeownership is becoming increasingly concentrated at the top of the K-shape, particularly among higher-income households and older generations.

At this upper end of the market, demand remains relatively stable, despite elevated home prices and mortgage rates. However, for first-time and entry-level homebuyers struggling with low wage growth, the effect is the opposite. 

Generational imbalance

NAR data shows that first-time homebuyers are disappearing in the United States. Baby boomers now account for a larger share of home purchases than millennials, despite millennials being the nation’s largest adult cohort.

According tothe analysis, first-time buyers account for just 21% of U.S. home purchases — near historic lows. Additionally, the typical first-time buyer is now 40 years old, highlighting how the timeline to ownership has shifted compared to prior generations.

As a result, older homeowners have been able to maintain purchasing power, leveraging decades of equity accumulation to outcompete younger buyers in bidding situations.

Sellers, too, are holding on to supply for longer, further constraining inventory. According to the NAR report, existing homeowners spend a median of 11 years in a house before selling — an all-time high.  

“The historically low share of first-time buyers underscores the real-world consequences of a housing market starved for affordable inventory,” added Lautz. First-time buyers today will both accumulate less wealth and move fewer times over a lifetime as a result.  

The growing divide 

Homeownership today is more unaffordable than it was at the peak of the 2006 housing bubble, according to the Atlanta Federal Reserve’s “Home Ownership Affordability Monitor” (HOAM). In fact, as of December 2025, the income required to afford a median-priced home ($398,667) is tens of thousands of dollars higher than what the typical U.S. household earns.  

HOAM’s Affordability Index shows the average household would need to spend roughly 42% of its annual income to purchase a median-priced home — well above the traditional 30% threshold.

That gap has expanded dramatically since 2021, effectively discouraging move-up buyers from purchasing and locking in existing homeowners into sub-4% mortgages. This has limited supply, leaving the market increasingly dependent on higher-income households and equity-rich repeat buyers.

“Affordability is the biggest trend, and it touches everything,” Brian Batten, division president of Lennar Homes, told Invest: Tampa Bay. “For the first-time homebuyer, we need to get home prices and the monthly payment down to a point where it is affordable for the majority of people.”

Regional bifurcation 

In competitive markets, investors are paying significant premiums, sometimes 35% above local median prices. Meanwhile, in more affordable markets, they are targeting lower-priced inventory, placing them in direct competition with entry-level buyers.

This is because investors face fewer headwinds than many typical buyers, according to Danielle Hale, chief economist at Realtor.com.

“With affordability still stretched and inventory tight, many would-be buyers remain sidelined, giving investors a larger share of the market and, in some areas, more influence over prices,” said Hale, as cited by National Mortgage Professional. 

As Hale explained, when investors focus on already competitive price ranges, it can push prices up even further, creating broader macroeconomic stratification and geographic imbalances. 

Performance gaps

As a result of these affordability gaps, the housing market is becoming increasingly unequal in terms of regional performance.  

“(We) have a market that continues to be very bifurcated,” said Selma Hepp, chief economist of the global information services company, Cotality. 

As Hepp observed, U.S. regions with stronger wage growth and labor markets have seen significant home price gains. By contrast, other markets — particularly those that had relied heavily on in-migration from wealthier households — are now facing greater instability. 

“On the flip side, you have markets that are now in this very uncertain situation because demand (and) in-migration to those markets has slowed,” she added.

According to Hepp, those areas depended on migration from those higher-income households. However, slower growth has led to more lower-income households relative to prior years, raising inventory levels (particularly those skewed to higher-price assets) and leaving conditions on less stable footing.

Barriers at the bottom 

For the bottom 50% of households (nearly 67 million homes), real estate wealth is an increasingly distant target.  According to a policy brief from the Ballard Center at Brigham Young University, this is mostly because of elevated home prices, limited starter-home supply, and higher mortgage rates. 

Housing economists widely agree that homeownership remains one of the most significant drivers of wealth in the United States. Yet, younger households now hold less wealth at comparable ages than previous generations did, limiting their ability to accumulate down payments.

The economic ramifications are significant, according to Jason Tigano, CEO of non-profit community advocacy group LEVEL Communities.  

In many metropolitan areas, for instance, the lack of affordable housing units means higher transportation costs and increased economic inequality, leading to less economic mobility and a widening wealth gap between generations.

“Areas with high percentages of homeowners have higher quality of life indicators, including education, health, civic engagement, and financial stability,” Tigano told Invest: Pittsburgh. “It’s about time we addressed this issue with a lasting solution.”

Like Tigano, NAR executive vice president and chief advocacy officer, Shannon McGahn, believes there are opportunities to rebalance the K-shaped housing market. 

“We need solutions that encourage more owners to sell, revitalize underused properties, streamline local zoning and permitting barriers, and modernize construction methods to build more homes faster and more affordably,” said McGahn in the analysis.
