A Private Pricing Opinion — what your apartment at The Walden 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.
The Walden is a seven-story condominium with 25 residences on East 130th Street. It combines a modest apartment inventory with part-time doorman service and a community room. The apartment mix includes ordinary single-level homes, a garden duplex and penthouse layouts with private roof space.
The building dates to the mid-2000s development period in Harlem. PLUTO gives 2004; the DOB new-building job was signed off in November 2005. Its 25-year 421-a benefit began in 2006 and remains active on the 2027 roll, placing the building within the later years of that original term.
The block between Madison and Park Avenues is east of the Lenox Avenue corridor. The building's residential and commercial interests share a single condominium structure, with the commercial space represented by a separate tax lot.
Architecture and unit composition
The recorded apartment inventory spans a wide range of sizes. Many single-level homes fall around 780 to 850 square feet, while larger apartments exceed 1,000 square feet. Upper-floor homes and the garden duplex supply additional layout categories within the same small building.
The interiors include high ceilings, hardwood floors and open kitchens. The original kitchen vocabulary includes stone counters and stainless-steel appliances. Renovations have since changed individual apartments, so interior condition varies across the resale inventory.
Penthouse layouts can include two bedrooms and one-and-a-half bathrooms, with private roof space arranged on two levels. One such roof installation includes a water connection and electrical outlets. Private outdoor space belongs to particular homes and is separate from the building's indoor common room.
The garden duplex places living space at the base of the building with access to a private outdoor area. Its vertical arrangement differs from the conventional single-floor apartments above. The building's larger interior areas therefore include more than one plan type.
Building operations
Part-time entrance staffing is supplemented by elevator service and shared facilities. Residents have common laundry and a community room equipped with a kitchen and bathroom, allowing the room to function separately from individual apartments. Bicycle storage and other storage space are also available.
The property has one commercial tax lot in addition to its 25 residential lots. A business operating in the commercial space is distinct from the condominium's resident amenity package.
The residential ownership roll is dispersed: no single owner holds more than one of the 25 homes. The active tax benefit follows its original 25-year term; it does not restart when an apartment changes hands.
Policy framework
Purchase structures: Co-purchasing and pied-à-terre ownership are permitted — confirm with the managing agent.
Subletting: Permitted subject to the condominium's procedures — confirm with the managing agent.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01755-7501) 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 from recorded condo declarations and offering plans.

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.
