A Private Pricing Opinion — what your apartment at 100 West 93rd Street (100 West / Leader House) 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.
100 West is one of the Upper West Side's clearest examples of a middle-income West Side Urban Renewal rental converted into a full-service condominium — built in the early 1970s as Leader House, then taken to condominium in 2006. The conversion delivered a large, professionally run building one block from Central Park at a per-foot well below the neighborhood's pre-war and new-construction stock, with condominium mechanics that the surrounding pre-war co-op alternatives rarely match.
The building's market thesis is value with flexibility: a Columbus Avenue address a block from the park, full building services, a signature roof deck, and a Trader Joe's downstairs, at a price basis that reads as a relative bargain for the location. For buyers who prize walk-to-park convenience and condominium latitude over pre-war detail, 100 West is a direct answer — and its relatively contained carrying costs are part of the appeal.
Architecture and unit composition
The building is a post-war modernist tower — a beige-brick, L-shaped mass set back within a landscaped plaza, with two piers of walled balconies animating the Columbus Avenue frontage. It is a building of its era: the architectural interest is in the massing and the plaza, not in ornament. The 279 residences run from studios through three-bedroom layouts, with higher floors capturing partial Hudson and Central Park views. Renovation quality varies line to line, and a meaningful share of the inventory traces to the 2006 sponsor sale.
Building operations
100 West runs as a full-service condominium: 24-hour doorman and concierge, a live-in resident manager, a fitness center, a residents' lounge, a children's playroom, central laundry with in-unit washer/dryers in many units, bike and private storage, and an on-site parking garage. The signature amenity is the roughly 17,000-square-foot landscaped roof deck — a genuinely large outdoor amenity for the neighborhood. The offering plan and current house rules are on file in The Roebling Research Library.

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 2020–25. 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.

What to know if you’re buying
The value is location plus flexibility. A Columbus Avenue address one block from Central Park with full condominium mechanics, at a per-foot below the surrounding pre-war and new-construction stock. Underwrite the comparison honestly.
The roof deck is a real amenity. At roughly 17,000 square feet, the landscaped roof deck is a genuine differentiator for the price point — factor it into the value.
Confirm the transfer mechanics on your specific unit. Many original sponsor-sold units transfer without board approval; resale units may carry standard condominium application steps. Verify the path for the line you are considering.
Condo flexibility is real. Pied-à-terre and investment use are permitted under the declaration; subletting is allowed subject to the by-laws; closings run on a condominium timeline of roughly 30 to 45 days.
Model the full carry. Common charges plus property taxes plus utilities and insurance — 100 West's relatively contained costs are part of the thesis; confirm the complete monthly number.
What to know if you’re selling
Lead with location, roof deck, and flexibility. The block-from-the-park address, the large landscaped roof deck, and the condominium latitude are your differentiators against the neighborhood's co-op stock.
Position against value-oriented UWS condos. Your comparable set is the surrounding full-service condominiums, not the pre-war trophy market.
Floor and exposure drive the spread. Partial-view high floors command the premium; interior and low-floor lines require realistic pricing.
Closing timelines are condo-fast. 30 to 45 days from contract to closing.

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.
