Right now builders are building for the upscale market, which leaves out folks who want to downsize or single or young people who want to start with smaller homes.  For this reason, a few builders are building small homes, but finding lots is a challenger.  Note that vacant lots scattered here and there are having smaller homes built on them.  One builder can build a 729 square foot metal home for $58,420 + $4,274 for the slab + the lot or land.  This keeps utility bills and monthly payments down and could be built in 6 weeks.  THEN MOVE UP LATER!!
