The building
239 East 79th Street is a post-war co-op in Yorkville on the Upper East Side, between Second and Third Avenues. Built in 1957 to designs by Maxon, Sells & Ficke, the 18-story building has 208 apartments and was converted to a cooperative in 1984.
239 is a full-service cooperative that offers newly updated hallways and a stylishly renovated lobby, creating a welcoming atmosphere. The pet-friendly building is supported by an exceptional staff, including a 24-hour doorman, a live-in resident manager, and an in-house handyman to cater to your needs. The recently completed roof deck is a true standout, designed with elegant and comfortable furnishings for lounging, dining, and relaxing. The building also has an onsite parking garage.
The location is great: just a few blocks from the 4/5/6 and the Second Avenue Q. Two new commercial tenants are coming into the building, Happy Tails dog daycare and Pop Up Grocer gourmet food store, which should be a great opportunity for income for the building.
The co-op permits financing of up to 75% of the purchase price (25% minimum down). Subletting is allowed after 2–3 years of ownership, with board approval, for up to 2 years. There is no flip tax. Pets are allowed; board approval for pets has been noted, so ask before you buy.
Maintenance runs approximately $2.20 per square foot per month, based on a sampling of apartments in the building. Actual maintenance varies by size, floor, exposure, and allocated co-op shares.
Every purchase needs board approval. Buyers submit an application package, including a financial statement with supporting documents, and then interview with the board. The process typically takes 30–60 days: under a new NYC local law, management has about 15 days to review the package and the board about 45 days to decide. Talk to Julio before you make an offer; he can walk you through how the board process works in practice.
