Brooklyn Condo Buildings Selling Below Market in 2026

Updated Oct 29, 2026 · 5 min read

Short answer: 11 Brooklyn condo buildings sold their apartments in 2026 for at least 10% less per square foot than comparable new condos. That's after adjusting for size, floor, bedrooms, outdoor space, finishes, amenities, tax break, subway distance and neighborhood. 6 of them still had homes the developer hadn't closed on as of September 2026, 61 in all.

The Buildings

"Comparable" is what our model expects the same apartments to sell for, based on sponsor sales in other Brooklyn new condos since 2021. Each building's figure is the median of its 2026 closings, and needs at least 3 of them.

Where the Gap Is Biggest

The Avanti in Flatbush closed its 2026 sales at a typical $775 per square foot, against $1,196 for comparable homes, 36% under. The building has repriced to the market: those closings ran 17% under the prices in the offering plan. Earlier closings in the building were $811 per square foot. 9 of its 45 homes hadn't closed yet.

Williamsburg Wharf on Kent Avenue is the largest building on the list with homes left: 25 of 89 hadn't closed. Its 2026 closings came in at a typical $1,644 per square foot, down from $1,909 in its earlier sales and 23% under comparable Williamsburg waterfront condos.

1479 Sterling Place in Crown Heights is a small new building whose first 6 closings came in at $910 per square foot, 24% under comparable homes, with 2 left.

Lumina in Sunset Park is the opposite case to The Avanti: it hasn't repriced; its plan prices were low for the neighborhood to begin with. Its first 7 closings came in at a typical $1,287 per square foot, 13% under comparable homes, and 19 of 26 homes hadn't closed.

Is It a Good Deal or a Worse Apartment?

A building can sell under comparable condos for reasons the records don't show: a busy avenue, no views, small windows, a difficult layout, a weak block. The model accounts for what's in the offering plan and the sales records, not what you see on a visit. Its estimate for any one sale is typically off by about 11%, so a building just past the 10% line is a lead to check, not a sure bargain.

Compare the building with itself. If 2026 closings are well under the building's own earlier sales, as at Williamsburg Wharf, its prices have reset to the market, and the homes still unsold are likely priced to match.
Read the latest amendment. Price changes for unsold homes are filed as amendments to the offering plan. See how to find them.
Check the monthly costs. A low price can come with high common charges or no tax break. Each building's page shows the plan's budget and estimated taxes.
"Not yet closed" isn't "available". Some of those homes may be in contract, rented out by the developer or held back. Ask the sales office what's actually for sale.

How This Is Counted

We took 283 Brooklyn sponsor (first) sales that closed in 2026 through September 2026, in 71 buildings: deeds recorded in NYC ACRIS, each matched to its apartment in the building's offering plan Schedule A, filed with the New York Attorney General. These are the same matched sales as our study of what Brooklyn condo buyers pay more for.

We estimated each sale's comparable price per square foot with a regression on Brooklyn sponsor sales since 2021: the apartment's size, floor, bedrooms, outdoor space and penthouse status; the building's amenities, finishes, size, tax program, common charges and distance to the subway; and the neighborhood and closing quarter. Each building's own sales were left out when pricing it, so a building can't set its own benchmark. Sales under 60% of their Schedule A price were left out as likely not market sales or not matched to the right apartment. 41 buildings had 3 or more 2026 closings; the list shows those whose median closing was at least 10% under.

Homes not yet closed are the plan's Schedule A homes less the sponsor deeds recorded in ACRIS. Limits: sponsor sales only, no resales. Square footage is the plan's interior figure. Deed prices don't net out concessions such as paid closing costs. Updated October 2026.
