I hate the baloney of so much per sq foot pricing. I built my home which is roughly 2700 sq ft for $110k but built it myself. The worst thing somebody can do is build in a development and use a developer. you are lining his pocket. Upgrades get expensive.
My advice is and when I started I could not cut a piece of wood straight. I was 22 yrs old but was determined to build my own home with very little mortgage. I drew my own plans, met with inspectors etc. We built the first 1500 sq ft all cash. The second 1200 sq ft had a $20k equity loan and roughly $35k cash. Anybody with half a brain can build a house that they can be proud of. Drive around to new home developments and check them out. Go to open houses and see what's new and great. I bet right now I could contract out most of a 2000 sq ft home that would be beautiful and be in the $250k range which would include sewer/septic, land etc. But.......you would be doing your own GC work, interior trim, plumbing, HW floors and electrical. I have been planning 2 houses for my kids and that is the range that I have been coming up with. Why be married to your wife AND a 30 mortgage ? If you cannot afford HW floors then put some semi-cheap laminate that say down the road in 5-7 yrs you can do all hardwood & tile. I have a 12'x12' cultured stone wall that I did in 1989 with no experience and it is still standing with no problems. Do not fall into the trap of nearly half a lifetime mortgage. And I am just a normal working stiff.
