Lynndee it all depends on what you put in the home and where you are going to build. You can build from under 100.00 a foot to the sky is the limit depending on your ammenities. I just closed monday on a new construction that came in at 115.00 a foot that was great. The home even had granite tops in all the bathrooms and a extra large 2 head shower in the master. Master walk in closet is about 14x16! They had a whole home sound system that added about 1.50 a foot, a deeper basement that added about 1.00 a foot, upgraded carpet that added about 1.50 a foot, brick design that added a 1.00 a foot, mud room/laundry room with coat closet that added about 3.00 a foot, the list goes on. So it all depends on what you want in the home and your future plans.
By the way use a RealtorÂ® to help you that is familiar with new construction as they may be able to save you a lot of money and head aches.
