Welcome to the Cellar Earthbound.
You're spot on with the McMansion scenario.
Up the street, big houses on small lots, selling for $300k+. They need a good security system because you can break in with a pen knife....no exaggeration. The walls have studs 24" on center with drywall on the inside and vinyl siding outside. Oh, and insulation. That's it! You could kick a hole in the damn wall.
The commercial buildings are not that much better. Rent a "pad site", throw it up, make some money then walk away with bankruptcy.
