Nearly two-thirds of home offers written by Redfin agents across the country in March faced competition, according to a new report from the discount brokerage. That’s up from a revised rate of 62.1 percent in February and marks the 11th consecutive month in which more than half of Redfin offers encountered bidding wars, as well as the second month in a row in which the bidding-war rate exceeded 60 percent.

Homebuyers have endured ruthless bidding wars during the coronavirus pandemic as low mortgage rates and remote work have compelled scores of Americans to relocate and buy homes. This has exacerbated an existing shortage of homes for sale, with buyers far outnumbering sellers. Bidding wars are so intense that a record 46 percent of homes are selling within one week of hitting the market, up from 30 percent a year ago.

Part of the increase, in addition to the traditional start of the spring house-hunting season, could be Americans looking ahead to a return to normalcy and back-to-school season, Redfin said.

Single-family homes had a bidding-war rate of 66.5 percent in March, making them the property type most likely to encounter competition.

Townhomes weren’t far behind, with a bidding-war rate of 65.6 percent. While condos were less competitive, more than half (51.1 percent) of Redfin offers still faced competition.

Single-family homes have attracted relatively fierce competition during the pandemic because homebuyers have been seeking out space and privacy, but townhomes may be starting to catch up. In March, the bidding-war rate for townhomes trailed that of single-family homes by less than a percentage point, compared with a 5.2-percentage-point gap in February.

Redfin’s report did not analyze sales in any of Connecticut’s three main real estate markets – Greater Hartford, Fairfield County and the New Haven-Milford area – but the company noted Salt Lake City had the highest March bidding-war rate of the 42 U.S. metropolitan areas in Redfin’s analysis, with 87.1 percent of offers written by Redfin agents facing competition. Next came Pittsburgh at 82 percent and Boise, Idaho, at 81.5 percent.

Homes listed between $800,000 and $1 million were the most likely to attract bidding wars, with 69.4 percent of Redfin offers facing competition in March. Next came homes listed between $1 million and $1.5 million, with 68.6 percent of offers seeing bidding wars.

Homes listed for less than $200,000 were the least likely to see competition, but still had a bidding-war rate of 59.1 percent.
