We are contemplating purchasing a 1949 house "to be moved" and having it moved to some acreage we own. It is rock faced and has 2 rooms built into the attic, with dormers, etc. The rock will be removed and the roof removed to move. Rather than replace the rock, we are looking at siding. I wondered what the price difference is between vinyl/aluminum and hardiplank. Also, if anyone has purchased and moved a home, I'd like any words of wisdom. Any horror stories?
