So you tare down a house. Rip up the foundation, rip out electrical, and plumbing services. You keep the fense, detached garage, and shed. You replace all electrical, gas, plumbing, pour a slab, frame it, new air &heating. New facade, roof, new fixtures, walls flooring.
You decide to sell it. I don't know about you guys, but I'm listing it as new construction, new home.
