I want to buy a house from a developer i looked the price of the home up and they bought it for 43k?

The developer bought the house for 43k they are selling it to me for 119.900 and i get a 10,000 tax abatement for ten years. Because i started buying the home early in the process they are letting me basically tell them how i want my house to be. They just stripped it down to the original framework and i wanted to know for resale purposes is it better to have 3small bdrms or 2big bdrms? and are they getting over with their resale price to me? considering i live in cleveland ohio is that too much?
