Nafco
NAFCO was very helpful to me. They even applied for and got my N#. There are various ways to handle the down payment. I basically bought the airframe kit and they sent a check for the engine and avionics which was my loan amount. I was real surprised that I could get a loan for an airplane that was basically 100's of parts, yet to be assembled. One thing to think about is that at the time of my loan they would only finance certified engines; ie. lycomings. That may have changed in the last 3 years. Good Luck, Jack
