I recommend Prospect Mortgage for a 203K lender, if you don't already have one in place. They have an entire department dedicated to nothing but 203K -
Best of luck, and please feel free to call me for contractors -

One of the contractors I recommend and have used personally recently did work for a buyer with a 203K loan. Contact me and I'll forward his information.
