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

Existing-home sales decreased for a fourth straight month in May, according to the National Association of Realtors®. Only one major U.S. region recorded a month-over-month increase, while the other three regions saw sales decline. However, each of the four areas again registered double-digit year-over-year gains.

Total existing-home sales (transactions that include single-family homes, townhomes, condominiums and co-ops) dropped 0.9% from April to a seasonally-adjusted annual rate of 5.80 million in May. Sales in total climbed year-over-year, up 44.6% from a year ago (4.01 million in May 2020).

"Home sales fell moderately in May and are now approaching pre-pandemic activity," said Lawrence Yun, NAR's chief economist. "Lack of inventory continues to be the overwhelming factor holding back home sales, but falling affordability is simply squeezing some first-time buyers out of the market.
 
"The market's outlook, however, is encouraging," Yun continued. "Supply is expected to improve, which will give buyers more options and help tamp down record-high asking prices for existing homes."

The median existing-home price for all housing types in May was $350,300, up 23.6% from May 2020 ($283,500), as every region registered price increases. This is a record high and marks 111 straight months of year-over-year gains since March 2012.

Total housing inventory at the end of May amounted to 1.23 million units, up 7.0% from April's inventory and down 20.6% from one year ago (1.55 million). Unsold inventory sits at a 2.5-month supply at the present sales pace, marginally up from April's 2.4-month supply but down from 4.6-months in May 2020.

Properties typically remained on the market for 17 days in May, unchanged from April and down from 26 days in May 2020. Eighty-nine percent of the homes sold in May 2021 were on the market for less than a month.

First-time buyers were responsible for 31% of sales in May, also even with April but down from 34% in May 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 May, even with April and up from 14% in May 2020. All-cash sales accounted for 23% of transactions in May, down from 25% in April and up from 17% in May 2020.

A new study released by NAR last week – the 2021 Vacation Home Counties Report – found that from January to April 2021, the share of vacation home sales to total existing-home sales rose to 6.7%. Vacation home sales jumped 57.2% year-over-year compared to the 20% year-over-year growth in total existing-home sales.
 
"The appeal of vacation homes has certainly grown during the pandemic, especially among employees permitted to work from home," Yun said. "As businesses decide new guidelines for remote workers, even allowing permanent remote options in some cases, look for vacation homes to remain a popular option."
 
According to Freddie Mac, the average commitment rate for a 30-year, conventional, fixed-rate mortgage was 2.96% in May, down from 3.06% in April. The average commitment rate across all of 2020 was 3.11%. Yun expects the 30-year fixed-rate mortgage to remain below 3.5% in 2021.
