A Private Pricing Opinion — what your apartment at 511 West End Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
511 West End Avenue is the kind of building that defines the corridor: a 1926 pre-war cooperative anchoring the southwest corner of West 84th Street, full-service, generously laid out, and protected within the Riverside–West End Historic District. West End Avenue is Manhattan's great residential boulevard — wider and quieter than Broadway, set one block in from Riverside Park, and lined almost entirely with substantial pre-war co-ops of exactly this vintage. 511 sits comfortably among them.
The building's appeal is the appeal of the corridor distilled. These are apartments built for a different scale of living — high ceilings, real entrance galleries, separate dining rooms, and the kind of room count that has become difficult to reproduce. With only two apartments sharing a landing on most floors, the residences carry a near-private feel, and the full-service staffing — a 24-hour doorman, a live-in resident manager, and a daytime porter — runs the building at the standard buyers expect on West End Avenue.
Architecture and unit composition
511 West End Avenue reads as a textbook example of the avenue's 1926 cooperative stock: a limestone base giving way to a brick shaft, restrained classical detailing, and a massing built for light and air rather than spectacle. The configuration — two homes per landing on most floors across 16 stories — produces large, gracious layouts with the entrance foyers, formal dining rooms, and well-proportioned bedrooms that pre-war buyers come to the corridor to find. A number of the upper homes capture open city and partial river exposures.
The building carries a children's playroom, central laundry, a bicycle room, and private resident storage — the practical amenity set that matters most to the families who anchor West End Avenue. Its position within the Riverside–West End Historic District protects both the building's own façade and the character of the blocks around it.
Building operations
511 West End Avenue is run as a full-service cooperative. A 24-hour doorman and a live-in resident manager are supported by a daytime porter, and the building maintains the playroom, laundry, bike room, and storage on premises. Financing is permitted up to 65% of the purchase price, and a modest flip tax assessed on a per-share basis is paid at closing. The building is pet-friendly. As with most pre-war West End Avenue cooperatives, the board reviews purchases through a full application and interview, and primary residence is the norm — the building is end-user-oriented rather than an investor's pied-à-terre market.

How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2025–30. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01246-0036) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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.
What to know if you’re buying
The building rewards buyers who want a true pre-war home on West End Avenue. Financing is capped at 65%, so plan for a down payment of at least 35% plus closing costs and reserves the board will expect to see. A per-share flip tax is paid at closing — budget for it in your numbers. The building is pet-friendly. Expect a full board application and interview: pre-war West End Avenue boards look closely at post-closing liquidity and debt-to-income, and the process is part of buying here. Primary residence is the expectation; this is not a pied-à-terre or investor building. The reward is space — the layouts here are larger and better-proportioned than almost anything in newer construction at comparable price.
What to know if you’re selling
Lead with the layout and the address. A well-proportioned pre-war apartment with an entrance gallery and a real dining room, in a full-service co-op on West End Avenue inside the historic district, is exactly what corridor buyers are searching for. Price to the West End Avenue pre-war comparison set — the relevant benchmarks are the other full-service 1920s co-ops on the avenue between the 80s, not Broadway condos or newer product. Prepare the buyer for the board. A clean, fully documented package moves faster through a pre-war board; we help sellers vet buyers for board-readiness before an accepted offer so a deal doesn't stall at the application stage. The building's two-per-landing privacy and full staffing are selling points worth foregrounding.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
