Sandro I wish you would have told me the exact address for this building.
There are three buildings there, 304, 314 and 324 on 41st. The 3 H's. I'm not sure which building you are referring to, I wasn't able to find a studio for a listed price of $285,000 in any of those 3 buildings.
This is what I have for your area of interest.
There is a 300sq studio priced at $295,000 in 25 Tudor City.
Another priced at $299,000 same building.
There is a studio in one of the H buildings that's priced at $229,000 but is only 225 sq ft.
Also a 250 sq studio priced at $250,000.
I was able to find two sales in that area since January 1st, which is going further back then your average comps of 2 to 3 months.
Studio sold in Turtle Bay for $244,500 no dimensions on the size.
And another studio sold on East 36th for $300,000.
Without an address and the actual apartment # this is the best I can do for you.
If I had to give you an answer right now, I think you might be a little low on your offer of $245,000. $40,000 on a small apartment is a big drop. That's about 13 to 14%. I don't know if the apartment you are interested in was priced above $285,000 originally, or is this the first price?
Sandro, you can email me with the information I asked for, and I'll be able to give you a better idea.
