I don't disagree that their are builders that are making somewhat slim margins even at these prices. But there are quite a few very established ones out there who have gotten really aggressive in the subcontractor market, us included. We are 80% commercial, but we use a lot of the same subs as the residential guys. If subs around here don't want to play ball at a reasonable level, we go find ones that will in markets like Houston. Being budget conscious and shopping around does pay dividends in a pretty big way. There is a lot of money to be saved when you start looking around at concrete, framing labor, drywall etc. And there is no sacrifice in quality if you pick the right ones.
We have a new individual coming in to our company that is looking for a ~3500 to ~3600 foot home in the $610k range max. After running comps at $180 to $197 a foot on recent sold listings, we decided he can buy a lot in IL and we will build him the exact same product all in at ~$530,000, lot included. This will include foam insulation, quality hand scraped flooring, trane HVAC system, double stage crown molding, premium vinyl low-e windows, commercial grade appliances, built in outdoor kitchen space on the patio, and everything else you are seeing on most of these builder spec homes.
