Homeownership has become harder to reach for the typical American household, and the numbers behind that shift have grown difficult to ignore. The National Association of Realtors’ Housing Affordability Index, one of the housing market’s most widely followed gauges, fell to its weakest level on record in data going back to 1989, reflecting the combined weight of high home prices, elevated mortgage rates, and income growth that has not kept up. That matters because the index is built to answer a straightforward question: can a family earning the median income qualify for a mortgage on a median-priced existing home? For much of modern housing history, the answer was yes. Recently, that answer has become far less certain, especially for first-time buyers trying to save for a down payment while monthly costs remain stubbornly high. Even households with stable jobs and rising pay have found that more income no longer stretches as far in the housing market as it once did. In practical terms, the squeeze is not just about sticker shock. It is about the growing gap between what buyers earn, what homes cost, and what lenders require in an era of higher borrowing costs.
How the Index Captures the Pressure
The National Association of Realtors’ methodology defines a reading of 100 as the point where a family earning the median income has exactly enough income to qualify for a mortgage on a median-priced existing home, assuming a 20% down payment. A reading above 100 means the typical family earns more than enough. A reading below 100 means it does not. That is what made the recent decline so notable. NAR said its affordability index hit a record annual low in 2023, and Bloomberg reported that monthly readings during that stretch also fell to record lows in the series. In other words, the typical family was no longer clearing the bar that this benchmark is designed to measure. Rather than simply signaling that housing feels expensive, the index showed that for many households, the math stopped working. The income side of that formula draws from official statistics, including U.S. Census Bureau income tables and American Community Survey data. Those figures provide a consistent baseline for tracking what households earn over time. The result is a measure rooted in actual family income, not sentiment or anecdotal evidence.
Prices and Paychecks Moved in Different Directions
On the housing side, the Federal Housing Finance Agency’s House Price Index shows how sharply home values climbed during and after the pandemic-era housing boom. FHFA’s index, which tracks single-family home values using repeat-sales data stretching back to the mid-1970s, has been one of the clearest indicators that price growth outran what many buyers could comfortably absorb. Wages did rise, but not enough to neutralize that surge. The Employment Cost Index from the Bureau of Labor Statistics, which measures hourly labor costs using a fixed basket of jobs, shows compensation continued to increase. Yet housing affordability is shaped by the interaction of income, home prices, and mortgage rates all at once. Stronger pay growth helps, but it does not fully offset the damage when home prices jump and financing costs remain elevated. That is where mortgage rates intensified the problem. Freddie Mac’s Primary Mortgage Market Survey shows that 30-year fixed rates climbed far above the ultra-low levels buyers became accustomed to earlier in the decade. Even if a home’s list price did not change, the monthly payment attached to that home changed dramatically once financing costs reset higher. For buyers on the edge of qualifying, that was often enough to push a purchase out of reach. The combined effect was brutal. Buyers were not simply confronting more expensive homes. They were confronting more expensive homes financed at more expensive rates, while income gains moved at a slower pace.
Why Lower Rates Alone Have Not Solved It
There is a popular assumption that affordability problems will fade once mortgage rates ease. That view misses how housing markets usually behave. Lower rates can reduce monthly payments, but they also tend to bring more buyers back into the market. When inventory remains tight, renewed demand can keep prices elevated or even push them higher again, erasing part of the benefit. That is one reason affordability has been slow to recover even when rates have improved from peak levels. The market is still dealing with years of undersupply. In many metro areas, builders have not delivered enough homes to keep pace with population growth, household formation, and changing living patterns. The Joint Center for Housing Studies of Harvard University has also highlighted the rise of single-person households, a shift that increases demand for housing units even without equivalent population growth. More households competing for limited stock naturally puts pressure on prices. For single earners in particular, the burden can be severe because they are trying to qualify on one income in markets where two-income households often set the pace. The Atlanta Fed’s Home Ownership Affordability Monitor points in the same general direction. Its higher-frequency affordability tracker offers a different framework than NAR’s measure, but it reinforces the same underlying reality: homeownership remains difficult for median-income households in many parts of the country.
Why the Gap Still Feels So Wide
Some housing measures have shown improvement more recently as incomes rose and mortgage rates eased from their highs. The White House and private-sector analysts have pointed to that progress, and those gains are real in a narrow sense. But improvement from extremely weak levels does not necessarily mean housing has become broadly affordable again. That distinction matters. An affordability gauge can move in a better direction while the median home price remains high, the down payment hurdle remains daunting, and buyers still face monthly costs that are far above where they stood just a few years ago. For households trying to enter the market for the first time, modest improvement can still feel like no improvement at all. National averages also blur local pain. Affordability looks very different in a lower-cost Midwestern market than it does in high-demand coastal metros where supply constraints, land costs, and zoning barriers are more severe. A family may hear that conditions are getting better nationally while seeing almost no relief in the city where they actually live and work. That is why the headline figure matters. The affordability index did not hit a record low because of one bad month or one isolated distortion. It reflected a market where prices rose faster than paychecks for too long, then higher mortgage rates made the gap impossible to ignore. Until supply improves meaningfully or incomes catch up more convincingly, the path back to broad affordability is likely to remain slow. For now, the most important conclusion is also the simplest one: the typical American buyer is still trying to purchase into a market that demands more than median earnings comfortably provide. That is the clearest reason homeownership feels less like a milestone and more like a financial stretch for a growing share of households.
