The concept of a Coop as an investment is less reasonable. If you mean that now is probably the best time to buy for a multitude of reasons including appreciation then I say yes, it's a good investmentand should be held for years. If you mean a good investment to rent then I would disagree as Coops are not the best investment vehicles in that regard.
In Jackson Heights there are many Coop buildings. I wish you all the best in your search. I'm sure you'll find something special.
It is on the 8th floor and is facing the back of the bldg. You cannot beat the convenience of the train station with the E, F, R, V and 7 trains and the bus terminal a few steps away. Aside from the food vendors, there are a plenty of great restaurants, supermarkets, and shops. This is a great location for young professionals and couples starting their families. You get A LOT more for your money in Jackson Heights.
