If you are not represented, the selling agent is not permitted to share information with you that would hurt the seller to whom they have a fiduciary responsibility.
I personally would like to see lower common charges and higher taxes (deductible). However, this is going to be your home. Do you feel at home in it? If so, buy it. If not, pass it by. It is not like a car that you will change in a few years...you are going to be living in this place every day and night. If you love it, it is a good deal.
Shoot me an email at work Tony, give me some more specifics and I can check what sold in that building in the past 6mo's to a year and for how much.
