new home

Ok this is not directly related to a brownstone house but i need some help. Today i looked at a new construction home a block away from Tompkins Park. The list agent works with Filmore and told me that the owner was asking 739,000. I got to the house and the agent from Filmore was not there so the owner showed me around. I must say that i was impressed. The first thing that you notice is the ceiling on the first floor i would say it's about 20 feet high. The house has 9 bedrooms and 5 baths with a finished basement. Ok lets get to the conclusion i brought up the question of price with the owner and he told me 799,000. what would be a good offer price considering if i went with him he does not have to pay 5 to 6 percent commission he would to filmore.

5% of 740k is 37k, so offer 703k and he would make the same amount as if the fillmore agent got his 5% fee at $740k.

but given the location, it is probably overpriced by 10%, so offer 630k.
