Manhattan Slips Below 5,000 Listings as the Market Hits Peak August

This was the quietest week of the summer: contracts fell on both timeframes in both boroughs, sentiment cooled across the board, and the pipeline flattened. The defining number sits on the other side of the ledger: Manhattan’s active inventory slipped below 5,000 homes for the first time this cycle, down 18.8% from last year after a seventh straight weekly decline, while Brooklyn holds below last year for a second week. The market is not loosening in the lull; it is freezing at the tightest levels of the year.

The Howard Hanna NYC Consumer Sentiment Index decreased from +28% to +11%, giving back the prior week’s rebound as the mid-August quiet set in: still positive, but the softest print since early July.

What This Means for the Last Month of Summer 2026

For buyers: This is the patient buyer’s window: the least competition of the year at open houses, and sellers of lingering listings are never more receptive than in mid-August. But run a two-track strategy, because selection is the thinnest of the cycle: negotiate firmly on homes that have sat, and move quickly on fresh, well-priced listings, of which there were only 127 in Manhattan this week, the season’s lowest influx.

For sellers: Buyer traffic is at its seasonal floor, so unless you need to transact in August, use these weeks to prepare a post-Labor Day launch: you will enter a market carrying nearly a fifth less Manhattan competition than last year. If you are listing now, price to the comps; discounts remain tight and disciplined pricing is still what moves.

Overall, this is a market on pause, not in retreat. Activity is quieter than last year for the first time this summer, but pipelines are holding near their highs and supply keeps setting lows. The fall market opens in three weeks from the tightest base of the cycle.

Manhattan Supply: Below 5,000 for the First Time This Cycle

Manhattan active inventory fell to 4,897 homes (−5.6% week-over-week | −18.8% year-over-year), a seventh consecutive weekly decline that takes the count below 5,000 for the first time this cycle and the year-over-year deficit to its deepest yet. New listings totaled 127 units (−8% week-over-week | −16% year-over-year), the thinnest weekly influx of the season.

Buyers now face nearly one in five fewer homes than last August, and with the new-listing tap at its seasonal minimum, the shelf the fall market opens from is already set. Every week of this decline raises the stakes on post-Labor Day pricing power.

Brooklyn Supply: A Second Week Below Last Year, and the Gap Is Widening

Brooklyn inventory decreased to 3,321 homes (−3% week-over-week | −3.5% year-over-year), a second consecutive week below last year’s level, with the deficit widening from −1.3% to −3.5% in a single week. New listings decreased to 112 units (−22% week-over-week | −13% year-over-year), a sharp pullback on both timeframes.

Brooklyn’s early-summer cushion has fully inverted: the borough that offered buyers extra choice in June now runs a growing deficit of its own. Supply is shrinking on the year in both boroughs at once, which is the tightest configuration this market has shown in 2026.

Pending Sales: The Pipeline Holds Through the Lull

The forward pipeline held its ground this week, flat to modestly higher through the quietest stretch of the calendar, a sign that deals in motion keep progressing even as new activity idles.

•       Manhattan pending sales: down −1.3% week-over-week to 3,996 units, giving back only a fraction of July’s build.

•       Brooklyn pending sales: up +0.8% week-over-week to 2,487 units, another fresh summer high for the borough.

Manhattan Consumer Sentiment: The August Floor

Manhattan recorded 166 signed contracts (−14% week-over-week | −17% year-over-year), the quietest week of the season on both timeframes as the vacation effect and 2026-high mortgage rates compound.

The Howard Hanna NYC Manhattan Consumer Sentiment Index decreased from +7% to −6%, slipping back below neutral. With the pipeline holding near 4,000 and supply below 5,000, the reading looks like the seasonal floor forming rather than demand walking away; the post-Labor Day prints will tell.

Brooklyn Consumer Sentiment: Cooler, Still Comfortably Positive

Brooklyn recorded 111 signed contracts (−9% week-over-week | −8% year-over-year), easing on both timeframes in the borough’s first negative year-over-year print since June.

The Howard Hanna NYC Brooklyn Consumer Sentiment Index decreased from +68% to +54%, a cooler reading that still leaves Brooklyn firmly positive and clearly the steadier of the two boroughs through the lull.

New Development Insights: A Quiet Board After the Woodside Surge

According to Marketproof data, new development activity recorded 24 signed contracts across 20 buildings during the week of August 10, 2026, settling back to the late-summer pace after the prior week’s Centric-driven spike. Top-performing developments included:

• The West Residences Club (Clinton, Manhattan) with two signed contracts

• Claremont Hall (Morningside Heights) with two signed contracts

After a month of outer-borough leaders, Manhattan projects top a quiet board this week, with demand spread thinly across 20 buildings rather than concentrated in one.
