The House-Price-to-Income Ratio Broke (5x Now)

One division tells you whether a housing market works. Take the median home price where you live, divide it by your household's gross annual income, and the result is how many years of pre-tax earnings the typical house costs. That is the house price to income ratio, and it is the most honest number in real estate because it cannot be argued with by a mortgage broker.

The national figure is about 5. It was about 2.5 in 1970. Nothing else in the affordability debate needs explaining once that is on the table.

What counts as a healthy ratio?

Housing economists generally treat 2.6x to 3x as the historically affordable band. Under 3, a median household can save a down payment in a reasonable number of years and carry the loan inside standard lending guidelines. Between 3 and 4, ownership requires discipline and a good rate. Above 4, the standard rules stop working. Above 5, most buyers need something other than their own income to close.

Here is the scale in plain terms.

Framework based on affordability thresholds commonly cited by housing economists; U.S. national figure from NAR and U.S. Census.

What is the U.S. ratio right now?

Roughly 5. The median U.S. home sells for about $400,000 to $420,000 (National Association of Realtors). Median household income is near $80,000 (U.S. Census, 2023).

That national average hides everything interesting. Coastal and supply-constrained metros run 8x, 10x, and higher, which is why professionals with six-figure salaries in those cities still rent. Parts of the Midwest and South remain closer to 3x, which is why interstate migration patterns shifted the way they did after 2020. The national number is an average of two different countries.

How do I calculate my own ratio?

Two numbers, one division.

Find the median sale price for your metro, which your county assessor, NAR's local board, or any major listing site publishes. Take your household's gross annual income before taxes and deductions. Divide the first by the second.

If the result is under 3, your market still works the way it worked for your parents. Between 3 and 4, expect to need a larger down payment than the standard advice suggests. Above 5, run the monthly numbers before you keep saving, because the target may be moving faster than your savings rate. That math is worked out for specific salaries in how much house you can afford on an $80,000 salary.

Why did the ratio double?

Prices and wages stopped moving together, and both halves were policy outcomes.

On the price side, homebuilding collapsed after 2008 and never returned to trend, leaving a shortage housing economists estimate in the millions of units. Local zoning across most residential land made the small, cheap house illegal to build, so the builders who did return built large. Institutional capital entered entry-level markets after the foreclosure wave. Each of those pushed the numerator up, and we trace them in why houses are so expensive.

On the income side, typical pay barely moved after inflation for decades while productivity climbed (Economic Policy Institute), and the federal wage floor has sat at $7.25 since 2009 (U.S. Dept. of Labor). The denominator walked.

A ratio only doubles if one term runs and the other does not. The historical starting point is in what houses cost in 1970, when the same division returned 2.5.

What does a 5x market do to a household?

It converts a savings problem into a sorting problem. At 2.5x, a household saves a down payment out of income and buys. At 5x, the down payment alone is roughly a year of gross earnings, the monthly payment at 6.5% to 7% rates (Freddie Mac) breaks the 28% guideline, and the price appreciates while the household saves.

So buyers reach for something outside their income. A family gift. Equity rolled from a prior home. A partner's entire salary assigned to the mortgage. NAR reports a growing share of first-time buyers using family money, which means the market now sorts by parental wealth rather than by earnings. Two people with identical jobs and identical savings rates get different outcomes.

The buyers who stretch to close anyway meet the second bill: taxes, insurance, and maintenance that the ratio never counted, itemized in the hidden costs of owning a home. Plenty of them end up house poor, holding the asset and nothing else.

Is the ratio broken everywhere?

The detachment is not uniquely American. The OECD tracks price-to-income as an index across member countries, and several advanced economies show housing prices pulling away from wages over the same period. What varies is the response. Some countries build aggressively at the entry level. Others restricted supply the way most U.S. metros did and got the same result.

That variation is the useful part. A 5x ratio is not a law of physics or an inevitable feature of a rich country. It is what happens when a place stops building the cheap house and stops raising the pay, then waits fifty years.

What would bring the ratio back down?

Both terms have to move, and only one of them is being discussed seriously in most places. Building enough housing, especially the small entry-level stock that zoning currently forbids, slows the numerator. Raising the wage floor that has been frozen since 2009 lifts the denominator. Do one without the other and the ratio barely budges, because a 10% price correction against flat wages still leaves a market at 4.5x.

The house price to income ratio is the affordability crisis compressed into a single figure, and it names the cause without editorializing: shelter detached from the wage that was supposed to buy it. No household overspent its way into a five-times-income market. The country built too few homes and paid too little for too long, and the ratio is just the receipt. The rest of that receipt, for healthcare, childcare, education, and retirement, is counted in the broken American Dream, and the policy decisions behind the housing half are traced in the housing crisis explained.
