What is housing affordability?
Housing affordability measures whether typical households can reasonably purchase or rent housing in a given market. The standard benchmark is spending no more than 30% of gross income on housing costs — including mortgage payments, property taxes, insurance, and utilities. When that ratio exceeds 30%, a household is considered cost-burdened.

Key facts
- The median price of a new home reached $412,300 in Q4 2025, roughly 4.7 times the 2025 median household income of $87,460.
- The 30% cost-burden threshold remains a standard measure used by federal housing policy.
- Mortgage debt service consumed 5.92% of disposable personal income as of Q4 2025, contextual evidence of the same payment pressure the American Distress Index's Debt Burden domain captures through the total household debt service ratio.
- FHA loans — typically made to first-time buyers with lower incomes — carried a delinquency rate of 13.64% in HUD's monthly report in August 2026.
- The NAR Housing Affordability Index dropped below 100 in 2022 for the first time since 2006, meaning the median-income family could no longer afford the median-priced home with a 20% down payment.

How Is Housing Affordability Measured?
Several complementary metrics capture different dimensions of housing affordability:
- Price-to-income ratio: Median home price divided by median household income. A ratio above 4 times is historically considered unaffordable. The current national ratio exceeds 5 times.
- Cost burden: Percentage of gross income spent on housing. Below 30% is affordable, 30-50% is cost-burdened, above 50% is severely cost-burdened.
- Payment-to-income ratio: Monthly mortgage payment (at prevailing rates) divided by monthly income. Lenders typically require this ratio below 28% for the front-end DTI.
- NAR Housing Affordability Index: Whether a family earning the median income can qualify for a mortgage on the median-priced home. Values below 100 mean they cannot.
Why Housing Affordability Has Deteriorated
Three forces have converged to create the worst affordability crisis in a generation:
- Price appreciation: Median new-home prices rose about 25% from Q1 2020 to Q4 2025, compared with about 29% growth in average hourly earnings for private-sector workers over the same period.
- Mortgage rates: Rates climbed from 2.65% in January 2021 to above 7% by late 2023, roughly doubling monthly payments on the same home.
- Supply shortage: The U.S. is estimated to be 3-5 million housing units short of demand, according to Freddie Mac and the National Association of Realtors.
The result is a "rate lock trap" — existing homeowners with sub-4% rates cannot afford to move, restricting supply further and keeping prices elevated for new buyers.
Affordability and Financial Distress
When households stretch to buy homes they can barely afford, they enter the distress pipeline that the American Distress Index tracks. Unaffordable housing costs compress other financial buffers: savings rates fall, credit card usage rises, and retirement accounts get raided for down payments. The ADI's Debt Burden domain measures required debt payments relative to income, and its Safety Net & Buffer domain measures the personal saving rate, with a lower saving rate indicating more strain.
FHA delinquency — 13.64% of FHA loans in HUD's monthly report in August 2026 — is one affordability signal in the data. FHA borrowers are disproportionately first-time buyers with lower incomes and smaller down payments. Their elevated default rates reveal what aggregate affordability indexes mask: the crisis is concentrated among the households least able to absorb it.
State-by-state differences
Housing affordability varies dramatically by state and metro area, driven by local home prices, property taxes, insurance costs, and income levels.
| State | Key difference |
|---|---|
| California | Among the least affordable states. Median home price exceeds $750,000 in many metros. Price-to-income ratio above 8x in coastal areas. Proposition 13 generally limits the base property tax rate to 1% and annual increases in assessed value to 2%, including for new buyers after purchase, although a purchase generally resets the assessed value to market value and new construction can also trigger reassessment. |
| Texas | More affordable home prices than coastal states, but among the highest effective property tax rates in the nation (1.36% of owner-occupied housing value in 2023), which significantly increases the total cost of homeownership. |
| West Virginia | Among the most affordable states by price-to-income ratio, with median home prices under $150,000. However, lower incomes and limited job markets create a different kind of affordability challenge. |
| Florida | Rapidly deteriorating affordability. Home prices surged 50%+ from 2020-2024 in many metros. No state income tax but escalating property insurance costs ($3,000-$10,000+ annually) add a hidden burden. |
| New York | Extreme affordability variance within one state. NYC metro price-to-income ratio exceeds 10x while upstate areas remain below 3x. Among the highest property tax rates nationally. |
Questions about housing affordability
What percentage of income should go to housing?
The widely accepted standard is no more than 30% of gross (pre-tax) income. Spending 30-50% makes you cost-burdened; above 50% is severely cost-burdened. A 28% front-end DTI is a conventional mortgage rule of thumb, while 31% is a baseline for some FHA manual underwriting. Qualifying borrowers may be approved for higher ratios.
Is housing more unaffordable now than before the 2008 crisis?
Rates alone don't settle it. The 30-year fixed rate in the weekly mortgage survey was 6.21% on January 5, 2006, and 6.80% on July 20, 2006. Comparing affordability with that period takes mortgage rates, home prices and incomes for both. The key difference: lending standards are tighter, so the distress manifests as inability to buy rather than mass defaults — so far.
What is the most affordable state to buy a home?
West Virginia, Mississippi, Arkansas, and Iowa consistently rank among the most affordable by price-to-income ratio. However, affordability depends on local job markets and income levels, not just home prices. A cheap home in an area with limited employment doesn't solve the underlying problem.
How does housing affordability connect to the American Distress Index?
The ADI measures budget pressure through multiple equal-weighted domains. The Debt Burden domain tracks required debt payments as a share of after-tax income. The Safety Net & Buffer domain tracks personal saving as a share of after-tax income, and a lower saving rate indicates more strain. The Delinquency domain captures the downstream effect when stretched homeowners begin missing payments.
What would make housing affordable again?
The math requires some combination of: higher incomes, lower home prices, lower mortgage rates, and increased housing supply. Most economists emphasize supply — the 3-5 million unit housing shortage is the structural driver. Rate cuts alone shift affordability without addressing the underlying price-to-income imbalance.
