Note: February 2021 data below are the most recent released by the National Association of Realtors.

Existing-home sales declined in February, following two prior months of gains, according to the National Association of Realtors®. Month-over-month, only one major region saw an increase in February, but all four U.S. regions recorded year-over-year gains.

Total existing-home sales (transactions that include single-family homes, townhomes, condominiums and co-ops) decreased 6.6% from January to a seasonally-adjusted annual rate of 6.22 million in February. Sales in total climbed year-over-year, up 9.1% from a year ago (5.70 million in February 2020).

"Despite the drop in home sales for February – which I would attribute to historically-low inventory – the market is still outperforming pre-pandemic levels," said Lawrence Yun, NAR’s chief economist.

He cautioned of a possible slowdown in growth in the coming months as higher prices and rising mortgage rates will cut into home affordability.

"I still expect this year’s sales to be ahead of last year's, and with more COVID-19 vaccinations being distributed and available to larger shares of the population, the nation is on the cusp of returning to a sense of normalcy," Yun said. "Many Americans have been saving money and there's a strong possibility that once the country fully reopens, those reserves will be unleashed on the economy."

The median existing-home price for all housing types in February was $313,000, up 15.8% from February 2020 ($270,400), as prices rose in every region. February's national price jump marks 108 straight months of year-over-year gains.

"Home affordability is weakening," Yun said. "Various stimulus packages are expected and they will indeed help, but an increase in inventory is the best way to address surging home costs."

Total housing inventory at the end of February amounted to 1.03 million units, equal to January’s inventory and down 29.5% from one year ago (1.46 million). Unsold inventory sits at a 2.0-month supply at the current sales pace, slightly up from January’s 1.9-month supply and down from the 3.1-month amount recorded in February 2020. NAR first began tracking the single-family home supply in 1982.

Properties typically remained on the market for 20 days in February, down from both 21 days in January and from 36 days in February 2020. Seventy-four percent of the homes sold in February 2021 were on the market for less than a month.

First-time buyers were responsible for 31% of sales in February, down from 33% in January and from 32% in February 2020. NAR's 2020 Profile of Home Buyers and Sellers revealed that the annual share of first-time buyers was 31%.

Individual investors or second-home buyers, who account for many cash sales, purchased 17% of homes in February, up from 15% in January and equal to the percentage from February 2020. All-cash sales accounted for 22% of transactions in February, up from both 19% in January and from 20% in February 2020.

"This year, we've seen fair housing protections extended, recognized Realtors®' remarkable volunteerism, and are collaborating with policymakers to increase revitalization endeavors in numerous neighborhoods," said NAR President Charlie Oppler, a Realtor® from Franklin Lakes, N.J., and the CEO of Prominent Properties Sotheby’s International Realty. "We have made an incredible amount of notable progress thus far in 2021, and NAR is committed and encouraged to continue those efforts."

According to Freddie Mac, the average commitment rate for a 30-year, conventional, fixed-rate mortgage was 2.81 in February, up from 2.74% in January. The average commitment rate across all of 2020 was 3.11%.
