Housing affordability is often discussed in absolutes — a $1.4 million median home in San Jose, a $900,000 median in Honolulu. But raw prices don't tell the full story. A $400,000 home in a metro where households earn $57,000 is more unaffordable than a $1.1 million home where incomes average $128,000. The metric that matters most is the price-to-income ratio: how many years of gross household income it takes to buy the median home.
A price-to-income ratio of 3.0 or below has historically been considered affordable — meaning a household can buy the median home for three years' worth of gross income. In the 1990s, the national average hovered around 3.2. Today it sits near 4.5, and in the metros below, it's two to nearly four times that threshold.
The Complete Top 20 Rankings
Using median home price data from Zillow (ZHVI) and median household income from the Census Bureau's American Community Survey, here are America's 20 least affordable metros:

The California and Hawaii Dominance
The pattern is unmistakable: 10 of the top 20 unaffordable metros are in California, and 3 are in Hawaii. Together, these two states account for 65% of the most unaffordable housing markets in the country.
This isn't simply about high prices — it's about the relationship between prices and local wages. San Jose has the highest median income of any metro on this list at $153,202, yet its $1.39 million median home still produces a 9.1x ratio. Meanwhile, Merced, CA — a small agricultural metro — has a comparatively modest $409,000 median home price, but household incomes of just $57,570 make it the 20th least affordable metro in America.
💡 Key Insight: The Inland California Trap
Central Valley metros like Merced and Salinas were historically "affordable alternatives" to the coast. No longer. Remote work migration, limited housing supply, and geographic constraints have pushed these once-affordable communities past the 7x threshold — unaffordable by any standard.
Beyond the Coasts: Surprise Entries
While the list is dominated by California and Hawaii, several non-traditional entries reveal the spreading affordability crisis:
- Bellingham, WA (8.16x): A college town near the Canadian border, Bellingham's scenic appeal and remote-work migration have pushed prices to $611,200 against modest incomes of $74,884.
- Boulder, CO (8.01x): Growth limits and an urban growth boundary have constrained supply for decades, producing California-level unaffordability in a Colorado college town.
- Bozeman, MT (7.58x): Montana's fastest-growing metro has become a symbol of the "Zoom town" phenomenon. Home prices rose 58% between 2019 and 2024.
- Coeur d'Alene, ID (7.58x): Once a hidden gem, this north Idaho lakeside community has attracted waves of migration from Seattle and Portland, more than doubling home prices since 2018.
What Does It Take to Buy?
Translating price-to-income ratios into practical terms: at a 7% mortgage rate with 20% down, a household in Kahului-Wailuku needs an income of roughly $185,000 to afford the median home. The actual median household income there is $83,691 — less than half of what's needed.
| Metro | Income Needed to Buy | Actual Median Income | Income Gap |
|---|---|---|---|
| Kahului-Wailuku, HI | $185,000 | $83,691 | -$101,309 |
| San Jose, CA | $275,000 | $153,202 | -$121,798 |
| San Francisco, CA | $218,000 | $127,792 | -$90,208 |
| Los Angeles, CA | $171,000 | $91,960 | -$79,040 |
| San Diego, CA | $171,000 | $103,674 | -$67,326 |
| Boulder, CO | $151,000 | $95,363 | -$55,637 |
How These Markets Compare to the National Picture
The national median price-to-income ratio is approximately 4.5x. Every metro in the top 20 exceeds this by at least 58%. The top five metros have ratios more than double the national average. For context, many of the most affordable metros in the country — places like Peoria, IL or Youngstown, OH — maintain ratios below 3.0x.

What Drives Extreme Unaffordability?
These 20 metros share common characteristics:
- Supply constraints: Geographic barriers (ocean, mountains) combined with restrictive zoning. Santa Cruz permits just 1.0 housing units per 1,000 residents per year.
- Desirable amenities: Coastal access, natural beauty, mild climates, and outdoor recreation attract high-earning remote workers who bid up prices.
- Wealth migration: All 20 metros have experienced significant in-migration from wealthier metros, particularly since 2020.
- Investor activity: High-amenity markets attract investor purchases, further reducing supply for owner-occupants.
The Building Deficit Connection
Many of the least affordable metros are also among the worst at building new housing. Santa Cruz-Watsonville has a permits-per-capita rate of just 1.0 per 1,000 residents — one of the lowest in the nation. By contrast, fast-building metros like St. George, UT (17.2 per 1,000) maintain far more reasonable price-to-income ratios despite rapid population growth.

What It Means for Residents
In these 20 metros, the practical consequences are severe:
- A majority of residents under 35 cannot afford to buy a home without family wealth transfers
- Essential workers — teachers, nurses, firefighters — are priced out of the communities they serve
- Long commutes become the norm as workers seek affordable housing further from job centers
- Homelessness rates correlate strongly with housing costs: 8 of the top 10 highest-homelessness-rate states contain metros on this list
🏠 The Generational Divide
In the top 5 metros on this list, a household saving 10% of the median income each year would need 22–27 years to accumulate a 20% down payment — assuming prices don't rise further. For comparison, the same calculation in 1990 would have yielded 6–8 years.
Methodology
Price-to-income ratios were calculated using Zillow Home Value Index (ZHVI) data for median home values and Census Bureau American Community Survey 5-year estimates for median household income. All 373 metros tracked by ShelterScope were ranked. Metros with populations under 50,000 were not excluded, as small metros can face severe affordability challenges (as Merced and Corvallis demonstrate).
