Market Cap of New Homes Continues Stumbling as Mortgage Rates Rise

The U.S. new home market continued stumbling along in May 2026.

Political Calculations’ initial estimate of the total value of new home sales in the United States during May 2026 is $28.62 billion. This value is slightly higher than the initial estimate of $28.30 billion for April 2026, which has been revised downward to $28.18 billion for this month.

This estimate rose largely because average new home sale prices have been rising, which have offset a falling number of sales in recent months as mortgage rates in the United States increased to near their highest levels in the past year:

The contract rate on a 30-year, fixed-rate mortgage — the most common U.S. home loan — climbed 7 basis points to 6.76% in the week ended July 24, just shy of a one-year high, the Mortgage Bankers Association said on Wednesday. The rate on 15-year, fixed-rate loans climbed 11 basis points to 6.15%, the highest in just over a year.

Meanwhile, rates on adjustable-rate mortgages, which can be a more affordable option in the face of high fixed-rate costs but come with the risk of a higher rate reset later on, also moved higher. The rate on a 5-year ARM edged up to 5.98% last week.

Looking at the big picture for the U.S. new home market, the following charts present the U.S. new home market capitalization, the number of new home sales, and their average sale prices as measured by their time-shifted, trailing twelve month averages from January 1976 through May 2026.

We’ll take a closer look at the impact these factors are having on the relative affordability of new homes being sold in the U.S. in the next week.
