I don`t know much about new home construction so don`t quote me but I think the reason we can`t find answers to this question is because there are so many things to consider. For example, a ranch will cost more because of the roof size. Plus all the finishing details, like marble, granite counter tops, etc. Each detail, big or small is a determining factor when building. I believe it also depends on the area in which you live. Also, I do know that it is cheaper to build up rather than out. So consider a two story home if cost is an issue. Good luck!
