228 West 21st Street

The three houses read as a unified composition: brownstone-faced fronts behind a gated entry, rising four stories over a basement that holds the laundry and storage. The nine apartments are predominantly floor-through in feel — one- to three-bedroom layouts with high ceilings, hardwood floors, and wood-burning fireplaces in many units; select units carry private terraces or garden access. As in most combined-townhouse co-ops, no two units are identical, and the spread between preserved-original and renovated interiors is the principal pricing variable. The 1910 date in city records describes the buildings' recorded vintage; the rowhouse fabric of the block reads older, and unit-level diligence should rely on the offering plan's building-condition statement on file rather than assumptions.

This is self-service ownership at its smallest workable scale: no doorman, no staff, a gated keyed entry, and a board of neighbors working with an outside managing agent. Review package logistics, walk-up access and the small board’s renovation process alongside current maintenance, included taxes, assessments and debt. Neither the staffing model nor unit count proves low costs or adequate reserves. The statements on file need dated review against the current capital plan; determine whether planned work is funded through reserves, assessments or borrowing.

Recent sales

Recent transfers 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. $/sf is measured on the latest sales with reliable square footage (2017): a median $1,477/sf (recorded) across 1 sale. The building has traded as recently as 2021. Median listing discount 0.0% from the last ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00770-0056). 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 on co-ops is not officially recorded, figures shown are approximate.

Underwrite the small-co-op mechanics first. Nine shareholders means concentrated governance: one major capital project, one difficult arrears situation, or one contested renovation matters more here than in a 200-unit building. Review dated financials and recent minutes, current reserves, debt and the capital plan; the statements on file do not by themselves establish present funding adequacy.

The conversion documents are the policy source. Sublet, pet, and alteration specifics are thinly documented publicly for a building this size. We verify against the offering plan, by-laws, and current board policies during diligence rather than relying on listing shorthand.

Fireplaces and outdoor space are the premium features. Wood-burning fireplaces are increasingly rare and effectively irreplaceable in new construction; units with terraces or garden rights carry a durable premium. Confirm that any fireplace is operational and board-permitted.

Expect walk-up reality and budget for character. Four stories, no elevator, and a 1910 building, so ask which house systems have been replaced and when. Run the Renovation Cost Calculator on any original-condition unit, and have your inspection cover the house systems, not just the apartment.

The financing convention is 20 percent down. Brokerage records document 80 percent financing permitted — generous for a co-op — but a small building will read the rest of your financial picture closely. Run the Co-op Board Qualification Calculator before offering.

Describe the apartment precisely. Townhouse floor-throughs with wood-burning fireplaces in a financially documented co-op, on a tree-lined Chelsea block two blocks from three subway lines — name the structural facts. Assess the buyer pool and competing inventory from dated sales and current listings; the building’s features alone do not establish demand or scarcity.

Get ahead of the small-co-op diligence. Buyers' attorneys will ask about reserves, the underlying mortgage, and capital plans. We provide the financial statements and conversion documents from the Research Library to serious buyers' counsel early, which keeps deals on track.

Anchor pricing to townhouse-co-op comps, not building averages. With nine units, same-building history is thin and often stale. Adjacent-block townhouse co-op sales — which we track — are the right comparables, adjusted for outdoor space and fireplace count.
