102 West 80th is a good Coop building, great location. The building also allows rentals. This is a factor you should consider when buying a unit. The ability to rent out your unit can be a plus if you get in to a financial bind or if you are an investor, but it also means that there can be a constant tenant turnover and strangers in the building - a concern if you are a Owner Resident. If you are interested in viewing units in this or other Manhattan buildings (Co-op/ Condo/ Townhouse), or if you wish to discuss this matter further, do not hesitate to contact me: Rona: 917-749-3571.
