Manhattan’s real estate market appeared to spring forward with the clocks in March.

New signed contracts and new inventory surged impressively last month, even taking into account the typical seasonal increase, according to a monthly report by Miller Samuel for Douglas Elliman.

“To see new listings finally enter the market in a consistent way suggests that we’re going to see a reasonable seasonal uptick in sales in the spring over the next several months,” said report author Jonathan Miller.

He noted that the numbers remain well below the year-ago levels, which were unusually high because the pandemic buying frenzy was still underway and the Federal Reserve had not started raising interest rates.

New listings have climbed consistently since December in the condo and co-op markets and new signed contracts in those markets have climbed each month since January.

In the one- to three-family market, new listings have increased for three consecutive months and new for two. New signed contracts in the borough increased 51 percent last month from February and new listings increased by nearly 35 percent, Miller said.

The successive months of new inventory hitting the market appears to be having an effect. Miller Samuel’s quarterly report for Manhattan found for-sale inventory in the first quarter was “essentially unchanged” from a year ago although sales were down nearly 38 percent.

“Typically when sales fall sharply, inventory surges, and that is not happening,” Miller said. “Which suggests to me there will be product to sell in the spring.”

In other words, if new listings continue to outpace sales, more supply is inevitable.

A similar trend is unfolding in Brooklyn, where new signed contracts for condos and co-ops rose sharply month-over-month. There were more than 300 new listings for condos last month, up from fewer than 200 in February, and roughly 200 new co-op listings, up from 120 in February.

Co-op contract signings more than doubled to over 120 from fewer than 60 in January, and new signed condo contracts saw a similar increase to just under 200, from just under 100 in February.

In the one-to-three family market, new listings have nearly doubled to roughly 360 in March from December, when there were about 180. New signed contracts increased for the second straight month.

Prices have been dropping compared to the year prior, a trend that could continue through the spring, according to Miller. Year-over-year comparisons will become more telling as the industry marks the one-year anniversary of the first interest-rate increases and the end of the Covid buying spree.
