21 Lefferts Place

The new-building application went to the Department of Buildings in January 2020, with sub-jobs for structural, mechanical, plumbing and sprinkler work. It describes a four-story building over a cellar with a roof level and six dwelling units. The Department of Buildings counts 4,478 square feet of construction floor area. PLUTO records 6 floors and 8,029 square feet of building area, a conflict we could not reconcile from public records. Structural work signed off in December 2025, mechanical in November 2025, plumbing in January 2026 and sprinklers in February 2026. We found no certificate of occupancy in the records pulled.

The residences run from one-bedrooms of about 525 to 530 square feet to a two-bedroom with two and a half baths of about 1,566 square feet and a three-bedroom of about 1,052 square feet, per listing records. City records show unit lots for 2F, 2R, 3F and 4, and listing records add a unit 1. The architect and developer are not documented, and no interior designer is credited.

Per the offering plan filed with the New York State Attorney General (plan CD230161), the plan was submitted June 20, 2023 and accepted October 7, 2025 with 21 Lefferts Place LLC as sponsor, and declared effective March 10, 2026. The record lists six residential units, an initial price of $5,319,000 and a current price of $6,790,000.

The Attorney General database returned an error when we pulled this record, so these figures come from our scan of September 27, 2026 and amendments were not reviewed. The scan shows two units sold. The city's sales file shows four closings by August 13, so the database is behind.

The Department of Finance sales file shows:

Sizes come from listing records. The four closings total $3.91 million. Units 2F and 3F closed at their asking prices. Unit 4 closed at $1.55 million against a listing at $1.7 million, 8.8% under. Unit 1, the two-bedroom of about 1,566 square feet, was listed at $1,850,000 on March 23, 2026 and at $1,750,000 on June 21, about $1,117 per square foot. We found no closing for unit 1 or unit 3R. Common charges in listing records run from $326 a month on a one-bedroom to $696 a month on unit 4. Treat both as unconfirmed. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,473/sf (recorded) across 5 sales. Median listing discount 1.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02014-7503; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

The plan is effective. Contracts are binding under the plan's terms and closings are under way. Read every amendment, and especially the one that raised the total price by 27.7%.

Price from recorded closings. One-bedrooms of about 530 square feet have closed at about $1,500 to $1,550 per square foot. The three-bedroom closed at about $1,473. The larger two-bedroom is priced near $1,120.

Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%) and the New York City real property transfer tax (1.425% above $500,000), plus the state mansion tax of 1% at $1 million and above. On the $1.55 million three-bedroom that is about $28,300 in transfer taxes and $15,500 in mansion tax before any gross-up. Homes under $1 million owe no mansion tax. Use the calculators below to run your price.

Certificate of occupancy. Closings began in May 2026 without a certificate of occupancy in the records we pulled. Ask whether it is temporary and what the sponsor holds back.

Carrying costs and abatement. The plan's budget sets common charges and projected taxes. No tax abatement has been confirmed here.
