My wife and I purchased one of the steel home kits from BudgetHomeKits.com. We did quite a bit of research, but decided to choose budget home kits because their homes allow you to assemble the home yourself without too much costly help.
Anyway, here's my Budget Home Kits review:
We bought a 2,800 sq ft home from them. Being very concerned about the price, we bought one of their Overstock kits. It arrived about one month later and they even gave us an orientation when they got there. I have to say that I was extremely relieved when they delivered the home kit. It just didn't seem real to me until I saw all of the steel.
Once we got started, it took about two or three weeks to assemble the outer shell of the home. My nephew helped me with this part. Then we moved on the the interior of the house. We did almost everything ourselves inside too. Budget Home Kits gave us all the interior plans, but we still got to choose our flooring, cabinets, fixtures, etc. My wife really shopped for bargains since we were on a tight budget. When it was all said and done, we were able to get the kit and finish our home for far less than if we had built a stick-frame home or if we had bought another steel home kit which require lots of contractors (and lots of money spent). The ability to assemble myself was the real money saver. And being able to pay-as-I-go for the interior finish out kept me from needing a 30 year loan.
I don't know if Budget Home Kits is for everyone. But it was certainly for us. Very rewarding and made us feel like pioneers. Beautiful home. Would do it again.
