This is strange, I've responded to your question and it didn't seem to go through, so let me try at it again.
I'm not sure if it's really possible to answer that question correctly for several reasons. You haven't specified which neighborhood you were looking in, because Down Town, Up Town, East Side or West will all be very different in prices for the apartments. Another factor would be the building type, is it pre-war or post, high floor or low and do you have views, also the size of the apartment. Does that building offer any services and amenities to it's residence or does it simply have a door man and that is it. As you can guess, the more amenities and services, the higher your maintenance charges will be and the opposite is true.
Few days ago our new 2008 Market report came out and I can send it to you in an email if you like to review it, it will give you further details.
Also here is a quick break down of prices.
Studio - $436,035 avg price
1 bed - $759,154
2 bed - $1641,764
3 bed is $4M plus.
This report is for the 2nd half of 2008.
I wish that I could have answered your question better, but you can see how thats difficult.
Do let me know if there is anything else thats on your mind.
