Land Lot Development - How much to pay?

[Jeremy Dyer]

I recently came across some Raw Land in Forsyth Area roughly a little more than 5 acres. I am not sure how to calculate if its a deal and how much of I should be paying. The newly constructed homes in the area are selling for around 185k at about 2000 sq ft on 5-6k sqft lots. Any feedback is greatly appreciated.

How many houses could you build per acre?

Approx cost per house to be built (if around 2k sqft)?

How much should I pay per acre?

What kind of development costs should I factor in?
