18 East 12th Street

The condominium reads as one address but lives as two joined pre-war loft buildings of 9 and 12 stories with roughly 59 feet of street frontage. The loft bones — deep floor plates, large windows, conversion-era ceiling heights — were cut into one- through four-bedroom apartments at conversion, and the inventory is defined by its irregularity: listing records document top-floor duplex and triplex penthouses, units with private terraces, skylit rooms, and interior balconies. Combinations have continued since (current city records count 37 residences against the plan's 38). Because no two units repeat, line-to-line comparisons matter less here than unit-specific features — outdoor space, level count, and light.

Full-service at boutique scale: full-time doorman, live-in superintendent, elevator service, a shared roof deck, private storage, and — unusually — laundry on each floor per listing records, with in-unit machines in select residences. The two commercial units at the base (roughly 5,200 square feet of retail per city records) are separately owned; the offering plan's special-risk disclosures note that the commercial units may be used for any lawful commercial purpose and that the board holds no right of first refusal over their sale — standard for the era, but worth your attorney's attention. The offering plan and by-laws are on file in The Roebling Research Library.

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 $1,309/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 2.9% 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 1-00569-7503; 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.

Understand the condominium structure. Pre-war fabric, doorman service, and condominium mechanics — no co-op board admission, and leasing permitted per the building's documented terms — in a corridor where the pre-war alternatives are co-ops. Use comparable sales to assess pricing, and confirm financing, pied-à-terre and ownership-entity rules in the current declaration, bylaws and house rules.

Buy the unit, not the line. Layouts do not repeat. A duplex with a terrace and a same-size simplex without one are different products at different prices. Use both relevant in-building sales and Village loft-condo sales, adjusting for unit-specific features and the age of each transaction.

Understand the commercial units. They are separately owned with broad use rights and no board right of first refusal, per the offering plan on file. Review the current tenancy and the by-laws' cost allocations with your attorney.

Reconcile the record dates. The offering dates to January 1985; city records carry a 1988 condominium application date. The documents on file resolve the timeline — we walk buyers' counsel through it during diligence.

Price the convenience honestly. Union Square's transit hub (4/5/6, N/Q/R/W, L) is three minutes away, with the Village's restaurant core in the other direction. For buyers weighing this block against quieter Village streets, the trade is access against bustle — visit on a Saturday before deciding.

Market the structural scarcity. "Doorman loft condominium, Fifth-and-University block" is a sentence very few Village buildings can say. Lead with the condo mechanics and the block; confirm pied-à-terre and ownership rules in the current declaration, bylaws and house rules before marketing them.

Compare the feature set. Evaluate terraces, duplex levels, skylights and renovation quality using comparable sales. Document alterations so counsel can review approvals and completed work.

Stage for the loft buyer. The building's appeal is character within a serviced envelope. Use floor plans and photographs to show scale, light and irregular geometry; no particular sales outcome follows from that presentation.
