We were originally planning to buy some property and put a modular home on it. Build a basement with an attached 3 car garage. It was going to be a triple wide. 36 x 72, very nice unit and the cost was around 130k. The lot was 80 acres. Total cost with septic and power and foundation, garage was around 300k. We couldn't get the financing on it because it was a construction loan.
Instead we got a stick built on 8 acres for around the same price.
For what you have invested, you have a very nice home. It looks like a modular to me. It's much nicer than what people classify as trailer homes. Be proud.
