Housing Affordability Holds Steady but Supply-Side Challenges Persist

Housing Affordability
Published

Housing affordability held steady at its lowest level in nearly a decade, as higher home prices offset lower mortgage rates to keep the affordability rate flat in the third quarter of 2021. However, ongoing supply-chain disruptions and the prospect of higher interest rates in the future threaten to exacerbate affordability problems in the months ahead.

According to the NAHB/Wells Fargo Housing Opportunity Index (HOI) released today, 56.6% of new and existing homes sold between the beginning of July and end of September were affordable to families earning the U.S. median income of $79,900. This is unchanged from the 56.6% of homes sold in the second quarter of 2021 and remains the lowest affordability level since the beginning of the revised series in the first quarter of 2012.

“Persistent building material supply chain bottlenecks and tariffs on Canadian lumber and Chinese steel and aluminum continue to place upward pressure on construction costs and home prices,” said NAHB Chairman Chuck Fowke. “Policymakers must fix supply chain vulnerabilities that are disrupting and delaying construction projects and hurting housing affordability.”

“Interest rates are anticipated to gradually rise in the coming months as the Fed begins to taper its monthly bond and mortgage-backed securities purchases,” said NAHB Chief Economist Robert Dietz. “To keep affordability problems from worsening in the future, policymakers need to tackle supply-chain challenges that are hindering new home production. Helping builders boost output will also slow the rapid rise in home prices that has occurred over the past year.”

The HOI shows that the national median home price increased to a record $355,000 in the third quarter, up $5,000 from the second quarter and $35,000 from the first quarter. Meanwhile, average mortgage rates fell by 14 basis points in the third quarter to 2.95% from the rate of 3.09% in the second quarter. However, mortgage rates are currently running above 3.1%, and this higher trend could affect affordability later this year and into 2022.

Lansing-East Lansing, Mich., was the nation’s most affordable major housing market, defined as a metro with a population of at least 500,000. There, 89.1% of all new and existing homes sold in the third quarter were affordable to families earning the area’s median income of $79,100.

An exception occurred in 2021, when new home size increased as interest rates reached historic lows. However, as mortgage interest rates increased in 2022 and 2023 and affordability worsened, demand shifted back toward smaller homes.
