Why Is Housing So Expensive in the US?

The question, stated fairly

"My parents bought a house when they were about my age. I have a decent job and I still can't imagine buying one. Rent keeps going up, too. What happened? Is somebody to blame?"

This is one of the most common questions Americans ask right now, and the frustration is understandable. Owning a home has long been part of the American dream. Let's look at what the official numbers show, then at the main reasons economists give, and where they disagree.

What the numbers show

All figures below come from government data published through the Federal Reserve Bank of St. Louis (FRED). Dates are listed.

1. Prices have risen faster than incomes. We compared the median sales price of houses sold (Census Bureau and HUD) with median household income (Census Bureau):

Year Avg. median home price Median household income Price ÷ income
1985 $84,275 $23,620 3.6
1995 $133,475 $34,080 3.9
2005 $236,550 $46,330 5.1
2015 $294,150 $56,520 5.2
2025 $415,400 $87,460 4.75

Prices are the average of that year's four quarterly figures; incomes are in current dollars for that year. The ratio is our calculation. The median sales price was $410,700 in the second quarter of 2026.

2. Borrowing costs jumped. The average 30-year fixed mortgage rate was 2.65% the week of January 7, 2021, and 7.40% the week of October 15, 2026 (Freddie Mac).

To see what that means, take a $410,700 home with 10% down. At 2.65%, the monthly principal-and-interest payment works out to about $1,489. At 7.40%, it's about $2,559. (This is our own arithmetic for illustration. It leaves out taxes and insurance.) Same house, roughly $1,000 more a month.

3. Rent has climbed faster than prices overall. The CPI index for rent of a primary residence rose about 2.5 times from January 2000 to September 2026. Overall consumer prices rose about 2.0 times (BLS, not seasonally adjusted).

4. We build fewer homes than at past peaks. Housing starts (new homes begun, at a seasonally adjusted annual rate) were 2,494,000 in January 1972 and 2,273,000 in January 2006. They fell to 478,000 in April 2009, after the housing crash. In August 2026 they were 1,275,000 (Census Bureau).

Why it happened: the main explanations

Supply hasn't kept up. When many people want homes and not enough are built, prices rise. After the 2008 to 2009 crash, home building fell sharply and took years to recover, as the numbers above show. Many economists see this long shortfall as a major cause.

Local rules make building hard. In many places, zoning laws limit what can be built: for example, only single-family homes on large lots, minimum parking requirements, height limits, or long permit reviews. Economists across the political spectrum have argued that these rules raise costs in high-demand areas. A widely cited 2002 study by economists Edward Glaeser and Joseph Gyourko found that in most of the country, home prices were close to the cost of building, but in a limited number of high-cost areas, "zoning and other land use controls, play the dominant role in making housing expensive."

Interest rates. Low rates around 2020 and 2021 made it cheaper to borrow and helped push prices up. When rates rose, monthly payments jumped. Many current owners also hold onto homes with low-rate mortgages, which keeps fewer homes on the market. A 2024 study by economists at the Federal Housing Finance Agency found that "for every percentage point that market mortgage rates exceed the origination interest rate, the probability of sale is decreased by 18.1%."

Construction costs. Building materials have become much more expensive. The BLS producer price index for goods used in residential construction rose about 56% from January 2020 to September 2026, while overall consumer prices rose about 31% (BLS, via FRED; our calculation).

Where people disagree

Economists debate how much each factor matters. Some emphasize zoning and supply. Others emphasize interest rates and investor buying. Still others point to local demand from job growth. Proposed fixes vary too: rent control, subsidies, building more, tax changes. Many economists warn that rent control can reduce the supply of rentals over time, while supporters say it protects tenants from sudden increases. These are honest disagreements.

What principles suggest

The American founding tradition puts a high value on property and on local self-government. That's a hopeful combination. Many of the rules that make building hard are made at the city and county level, which means ordinary citizens can show up, speak up, and change them. Allowing more homes to be built, while respecting neighbors' rights, is a solution that people from many viewpoints can support.

What you can do

  • Look up your local zoning rules. Find out what can legally be built where you live.
  • Attend a city council or planning meeting. Local decisions about housing are often made with very few people in the room.
  • Ask candidates at every level: "What will you do to let more homes be built?"
  • Check the numbers yourself using the free sources below.

Homes didn't get expensive overnight, and they won't get cheaper overnight. But this is a problem citizens can actually influence, and that's a good reason for hope.
