IRC homes are built to the same exacting codes as local conventional "site built" homes and are considered inter-changeable with them. They appraise and are financed using conventional loan programs using your neighbors "site built" home as comparable's. They sell however at huge pricing discounts off from local builders, saving you approx. 20-40% from conventional building and saving you $1000's of dollars in construction interest and frustration. No steel remains under these homes after transport just like a conventional home.
