The share of flips among second-quarter home sales was up in Greater Boston, according to a new report, but flippers’ return on investment was down significantly over 2021.

An analysis of metro area-level data by real estate analytics firm Attom Data shows 935 single-families and condominiums were flipped in the Greater Boston metropolitan statistical area between April and June of this year, or 5.4 percent of all sales during the period. That’s nearly 40 percent above the same quarter last year, and a record high.

Attom designated any residential property that sold in two successive arm’s-length transactions within 12 months as a flip.

Flippers bought the properties at a median price of $450,000 and sold them for a median price of $610,000, for a gross profit of $160,000, excluding rehab and other costs. While that represents a return on investment of 35.6 percent, it’s down from the 41.5 percent ROI flippers were earning one year prior.

The time it took flippers to do their work also increased over the second quarter of2021: from 175 days to 191 days.

Springfield saw similar trends: 7.2 percent of that area’s home sales were flips in the second quarter of this year, 39.8 percent up from the second quarter of 2021, and sold for a median price of $280,000. That represented a 35.9 percent return on initial investment, down from 66.7 percent in the second quarter of 2021. Days-to-flip went up only slightly, however, from 183 to 189.

In Worcester, 5.6 percent of sales were flips in the second quarter, up just 14 percent year-over-year, and selling for a median price of $352,483. That price represented a 41 percent gross ROI, down from 55.3 percent one year ago. Days-to-flip went up from 182 to 190.

Nationally, flips represented 8.2 percent of all home sales in the second quarter of 2022, up from 5.3 percent at the same time last year but the third-highest level since 2000, excluding the first quarter of this year when 9.7 percent of sales were flips. Typical profit margin was 29 percent, down from 33 percent a year earlier and below the prior peak of 53.1 percent set in 2016.

“The second quarter was another strong showing for fix-and-flip investors. The total number of properties flipped was the second-highest total we’ve recorded in the past 22 years, and the median sales price of a flipped property – $328,000 – was the highest ever,” Rick Sharga, executive vice president of market intelligence for Attom, said in a statement released along with the data. “The big question is whether the fix-and-flip market will begin to lose steam as overall home sales have declined dramatically over the past few months, and the cost of financing has virtually doubled over the past year.”
