I agree with Plano that it's easier to negotiate once the homes are built and the builder wants them to go. As far as which square footage would be right. I've lived in a 1,350 sq ft, a 3,000 sq ft, and now a 1,900 sq ft house. Each of them can be comfortable, though I'd say 1,900 is the most comfortable to me. It depends on what you can qualify for in a mortgage, of course. If there are deals to be made, I'd go with the bigger of the two. If there comes a time when you would like to sell your home, the larger home will be more attractive to buyers, and not considered one of the "affordable" models in the development. Also, builders tend to put some nice little touches in the bigger homes.
