If you remember one number about housing affordability, make it the price-to-income ratio. It tells you more about a market’s health than the median home price ever will.
What It Is
The price-to-income ratio divides the median home price by the median household income.
Ratio = Median Home Price / Median Household Income
A ratio of 3.0x means the median home costs three times the median annual income. Historically, 3-4x has been considered affordable. Above 5x is stretched. Above 7x is severely unaffordable.
The National Trend
| Year | Ratio | Assessment |
|---|---|---|
| 1990 | 3.4x | Affordable |
| 2000 | 3.9x | Moderate |
| 2006 | 5.1x | Peak (pre-crash) |
| 2012 | 3.5x | Reset post-crash |
| 2020 | 5.0x | Climbing again |
| 2026 | 5.4x | Above 2006 peak |
The current ratio exceeds the 2006 peak that preceded the housing crash. The difference is that today’s elevation is driven more by supply constraints than by speculative lending. That makes it more sustainable but doesn’t make it affordable.
State-by-State Ratios
HomeStats calculates the price-to-income ratio for every state. Visit any state page to see the current ratio alongside the affordability gap.
Most Affordable (Lowest Ratios)
States where homes remain affordable relative to local incomes:
- West Virginia (~2.5x)
- Mississippi (~3.5x)
- Iowa (~3.2x)
- Indiana (~3.3x)
- Ohio (~3.4x)
Least Affordable (Highest Ratios)
States where homes are severely stretched relative to incomes:
- Hawaii (~8.2x)
- California (~7.5x)
- Massachusetts (~5.8x)
- Washington (~5.9x)
- Oregon (~5.5x)
Why It Matters More Than Price
A $500,000 home sounds expensive. But if the median household income is $150,000, the ratio is only 3.3x and the home is quite affordable. Meanwhile, a $200,000 home in an area where the median income is $40,000 has a ratio of 5.0x and is actually less affordable.
Price alone is meaningless without income context. The ratio normalizes price against local earning power.
What Drives High Ratios
Supply constraints: Markets with limited buildable land (islands, dense coasts) can’t add supply to meet demand.
Demand concentration: Job centers attract high-income workers who bid up prices beyond what local median incomes can afford.
Investor activity: Markets attractive to investors (vacation areas, Sunbelt growth) see additional demand that isn’t tied to local income.
Rate lock-in: Homeowners with low mortgage rates don’t sell, reducing supply and keeping prices elevated even as demand softens.
Historical Corrections
When the ratio climbs above 5x, historically one of three things happens:
- Prices decline (2008-2012): Forced selling from bad loans pushed prices down 30-40% in overheated markets
- Incomes catch up (takes decades): Gradual income growth eventually normalizes the ratio
- Stagnation (Japan 1990s): Prices flat-line for years while incomes slowly close the gap
The current situation most resembles option 3 in many markets: prices too high to keep rising but not enough forced selling to cause a crash.
