I'm going to update this for future searches of USDA.
First, if you are of moderate circumstances, a USDA Home Loan will get you a zero down loan for a house in a rural area. The interest rate and terms are fantastic. There is an upfront fee, but nowhere near stupid PMI. USDA is an unrecognized home loan jewel, but sometimes they run out of money and you get to wait.
You need decent credit, and your income needs to be pretty low. I've helped a few people get these recently, and their county limits were approx $45,000/$47.000 net income. YMMV.
Anyway, to answer my own original question: They changed the rule, and you can use any contractor you want. They have to get approved by the USDA if they aren't, and if your state requires a contractors license, they must have one. It's easier to use someone already approved. Just look for someone you can bend to your will.
