[Broken Arrow]

To me, the biggest obstacle in home-building is the plumbing, electricity, and foundation work. The first two either requires certification or they don't come cheap.

Otherwise, the framing of the house itself isn't that difficult....

I'm not saying this can't be done, nor am I discouraging anyone else from doing so. I have seriously considered taking a similar path, and I'm just stating what I think are the challenges involved.

Oh, and I also want to add another interesting option to consider: Habitat for Humanity. It's a good charitable organization where you volunteer yourself to help build houses, and in return, you are also eligible for one of their houses with a great discount. One of my sisters volunteered to help re-build houses in New Orleans, and in return, she got a great deal on one of their houses down there.
