I'm also curious about this building. I've seen a lot of listings online there recently and it appears the building has some nice amenities (roof deck!) and is well maintained. It does always concern me when I see a lot of units for sale in one building. As per StreetEasy, there are currently 6 active units, 4 of which are in contract. As this is a 52 unit building, this is more than 10% of the units. There were also a few recent sales and 1 or 2 attempted sales that delisted in 2020. It makes me wonder if people are fleeing the building or if it is just a coincidence.
I've never been inside and I don't think I know anyone that lives there. It's definitely not the prettiest block in Jackson Heights, but it is definitely the nicest building on that block (at least from the outside). It's also close to the subway, which is nice.
Best of luck in your search!
