Why Today’s Home Buyers Face a Tougher Math Problem Than Their Parents Did

Comparing today’s mortgage rates to the 14% rates of the 1980s misses a key part of the affordability story, according to an analysis by financial commentator Ted Jenkin: home prices have grown far faster than incomes, making the overall cost of buying a house much steeper than a simple interest-rate comparison suggests.

In 1984, the median new home sold for about $79,900 while median household income was roughly $22,400 — a home-price-to-income ratio of about 3.6 times income. The average 30-year mortgage rate that year was 13.9%.

By 1990, that ratio had climbed to about 4.1 times income, with the median new home costing $122,900. In 2000, the ratio held near 4 times income even as mortgage rates stayed above 8%. By 2010, the median new home cost roughly 4.5 times median household income. By 2020, it was approaching 5 times income, with homes at $330,900 against household income of roughly $68,000.

As of August 2026, the median existing home price stood at $429,100, against a median household income of $87,460 for 2025 — about 4.9 times income. The average 30-year mortgage rate hit 7.40% on Oct. 8.

The down payment gap

The analysis points to the down payment as a particularly overlooked burden. A 20% down payment on the $79,900 home in 1984 came to about $16,000, or roughly 71% of that year’s median household income. Today, 20% down on a $429,100 home is nearly $86,000 — about 98% of median household income, before closing costs, moving expenses or furniture.

Borrowing the remaining $343,000 at 7.28% produces a principal-and-interest payment of roughly $2,350 a month, before property taxes, homeowners’ insurance, HOA fees and maintenance are added in.

Orange County’s affordability squeeze

The pressure is especially visible in Orange County, California, where state officials have classified a $104,200 salary as “low-income” given local housing costs — an example cited as evidence of how far home prices have outpaced what counts as a comfortable income in high-cost regions.

Taken together, the analysis argues that today’s buyers are squeezed from several directions simultaneously: home prices relative to income, the cash required for a down payment, and the cost of borrowing once a mortgage is secured. That combination, rather than the interest rate alone, is what separates the current housing market from the one previous generations navigated.
