Single-family home prices increased at a non-seasonally adjusted annual rate of 4.7 percent from Q1 2022 to Q1 2023, down from the previous quarter's revised annual growth rate of 8.6 percent, according to Fannie Mae's (OTCQB: FNMA) latest Home Price Index (FNM-HPI) reading, a national, repeat-transaction home price index measuring the average, quarterly price change for all single-family properties in the United States, excluding condos. On a quarterly basis, home prices rose a seasonally adjusted 1.0 percent in Q1 2023, above the 0.0 percent growth seen in the prior quarter. On a non-seasonally adjusted basis, home prices also increased by 1.0 percent in Q1 2023.

"As expected, the annual rate of increase in home prices has slowed dramatically in response to the rapid and significant increase in interest rates," said Doug Duncan, Fannie Mae Senior Vice President and Chief Economist. "Still, the fact that prices rose slightly in the first quarter is evidence of significant pent-up mortgage demand, despite ongoing affordability constraints. Even though mortgage rates remain elevated compared to the previous few years, the acute lack of housing supply remains supportive of home prices. Of course, the shortage of homes for sale is currently being exacerbated by the so-called 'lock-in effect,' which continues to disincentivize huge numbers of households with low mortgage rates from listing their homes."

The FNM-HPI is produced by aggregating county-level data to create both seasonally adjusted and non-seasonally adjusted national indices that are representative of the whole country and designed to serve as indicators of general single-family home price trends. The FNM-HPI is publicly available at the national level as a quarterly series with a start date of Q1 1975 and extending to the most recent quarter, Q1 2023. Fannie Mae publishes the FNM-HPI approximately mid-month during the first month of each new quarter.
