357 Prospect Place

The building fills a 3,638-square-foot lot with about 7,700 square feet of residential space. The unit designations run two on the first floor (1A, 1B), one on the second (2A), two on the third (3A, 3B), and one each on the fourth and fifth (4A, 5A). The Department of Finance roll puts 1A, 3A and 3B between about 680 and 790 square feet. 1B, 2A and 4A are about 1,430 square feet each, and 5A is about 1,160. The single-letter floors and the matching 1,430-square-foot sizes suggest some of these apartments are duplexes, and listing records do describe duplex layouts. Listing records also describe private outdoor space, including balconies and a garden. The roll does not show which units have them, so confirm each unit's outdoor space against the declaration and floor plans.

The five storage lots (ST-A through ST-E) are separate condominium units. Four were conveyed together with apartments at the 2016 closings, and a storage lot has changed hands alongside at least one resale. If the apartment you are buying comes with storage, it is a separate deed and tax lot, so make sure the contract names it. One storage lot (ST-A) appears in ACRIS but not on the 2027 roll. Ask the managing agent how it is held now.

Listing records describe the finishes: white oak herringbone floors, stone baths, individual heating and cooling systems, and a video intercom. The facade is contemporary among nineteenth-century rowhouses. Because the lot is outside the historic district, exterior work does not need LPC approval.

A seven-unit condominium with no staff has a board of managers drawn from the owners; the scale of its common-charge budget must be established from current records. It has no doorman or superintendent, and no resident manager is documented. The elevator, roof and building systems are about ten years old; their current condition and the timing of capital items such as elevator modernization and roof membrane replacement need confirming. No offering plan, budget or financial statement for the building is on file in The Roebling Research Library. Reserves, insurance and any assessment history must come from the managing agent.

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 (2025) cleared a median $1,549/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount -1.8% over ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01153-7502; 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.

Underwrite from the current bill. No 421-a benefit appears on any roll on file, so no 421-a phase-out is scheduled; check the apartment's tax bill for any other abatement. Assessments on the unit lots have still risen year over year on the recent rolls. Pull the current tax bill for the specific unit and the last three years of assessed value.

Confirm storage and outdoor space by deed. Storage units are separate tax lots. Outdoor space is allocated by the declaration. Neither shows up in the apartment's lot number.

With seven owners, one vote matters. Every owner's common-charge payments and every board decision weigh heavily. Ask the managing agent for arrears, the reserve balance, and any planned or past assessments.

The record has errors. PLUTO shows four floors and 2014. DOB shows five stories and a 2017 final certificate of occupancy. Lenders and appraisers sometimes pull the PLUTO figures, so check that the appraisal uses the correct ones.

Lead with elevator, condominium, no sponsor. Buyers comparing small new developments in Prospect Heights often find sponsor-held inventory or an abatement about to phase out. Neither applies here, so say it plainly.

Price against boutique new construction, not brownstone floor-throughs. Buyers here also consider brownstone floors nearby, but those have no elevator and often co-op ownership. The better comparables are elevator condominiums built after 2010.
