The standard affordability guideline used by most lenders places housing costs — mortgage payment, property taxes, and insurance — at or below 28% of gross monthly income. This threshold, sometimes called the front-end debt-to-income ratio, provides a reasonable approximation of what most households can sustain comfortably over time.

Applying this guideline to median home prices by state, combined with current mortgage rates and average property tax and insurance costs, produces a picture of required income that varies dramatically across the country — and that has shifted substantially as home prices and interest rates have moved over the past several years.

The most affordable states by income requirement

West Virginia consistently ranks as the most affordable state by this measure. With a median home price around $175,000 and relatively low property taxes and insurance, the income needed to comfortably afford a median home with a 20% down payment is approximately $45,000 to $55,000 per year at current rates.

Mississippi, Arkansas, Iowa, and Indiana round out the most affordable markets, each requiring roughly $50,000 to $65,000 in annual household income to meet the 28% guideline on a median-priced home. These states combine low home prices with moderate taxes and insurance costs.

It is worth noting that median home prices in these states also tend to reflect lower average incomes. Affordability by the income-to-price ratio does not necessarily mean these areas are more accessible to their local residents — median incomes in the lowest-cost states are also lower than the national average.

Where income requirements are highest

California, Hawaii, and Massachusetts have income requirements that place homeownership out of reach for a substantial portion of their populations. In California, the median home price across the state is approximately $750,000, requiring an annual income of roughly $185,000 to $220,000 at current rates to meet the 28% guideline — depending on county-level property taxes and the size of the down payment.

Hawaii presents an even more acute picture. With median home prices approaching $800,000 and some of the most expensive utilities in the country, comfortable affordability requires income well above $200,000 annually for a median-priced home.

New York, New Jersey, Washington, and Colorado also carry significantly elevated income requirements — ranging from roughly $120,000 to $180,000 for a median-priced home depending on the specific metro area within each state.

How mortgage rates change the picture

The income required to afford any given home price is directly tied to the mortgage rate at the time of purchase. A 1% change in the interest rate on a $400,000 loan changes the monthly payment by approximately $225 to $250. Across the life of a 30-year loan, that difference compounds to well over $80,000 in total interest.

At the lower rates that prevailed in 2020 and 2021 — when 30-year fixed rates dipped below 3% — the income required to afford today's median home prices would have been roughly 20% to 30% lower than it is at current rates. The combination of rising prices and rising rates between 2021 and 2024 produced the most significant affordability deterioration in several decades.

This dynamic is why the share of first-time buyers in the overall market dropped to a historic low of 24% in 2024, down from 32% the prior year and well below the historical norm of around 38% to 40%.

The 28% guideline is a starting point, not a ceiling

Lenders use the 28% front-end ratio as a qualification threshold, but household financial situations vary considerably. Some buyers carry significant student loan debt, car payments, or other obligations that affect what they can comfortably sustain at any given income level. Others have unusually stable employment, substantial savings reserves, or other factors that make a higher housing ratio manageable.

The Am I Ready to Buy tool on this site assesses readiness based on the full financial picture — income, debt load, savings, credit score, employment type, and planned time horizon — rather than the single income-to-price ratio. The result includes a readiness score, an affordable price range estimate, and the specific factors most likely to affect qualification for a given buyer's situation.
