If you can swing it, build it yourself. I built my own house 2800 ft for under $40/sq ft. That was in 2001 when lumber prices were a hell of a lot higher than now, other than particle board which is at a real high, not sure the reason for that other than greed.
Paying someone $6000 to shingle a house in a day or $6000 to side a house in 2 days or $14,000 to mud and tape 2 floors in 3 days is insane.
Take the time, learn a few trades and do it yourself like I did. Start to finish it took me 7 months and I saved I would guess $250,000.00 - $350,000.00. Then a couple years later I built my shop, 40x50x12 and saved another $100,000.00. I had guys begging me to build shops for them here.
When I built my house, I was also running my main business, and was running the arena. I would get up at 5am, go work on the house until 4pm, run the arena until midnight and get a few hours sleep. Repeat until the house was done and saved how many thousand per day?
My only costs were feeding friends and family that helped, $2000 for blow-in insulation and $500 to get a guy to tape and mud the basement in 2 days. It's real good to know 'a guy'. I had friends that knew how to survey the footings, neighbor dug the basement with a payloader for $500. I had a floorlayer do the lino and carpet for $500 as well. As much as they want you to think all of this is rocket science, it is not.
I took out a homeowners permit for the gas, electric, heat. Minimal cost. Nelson lumber did the Blueprints.
Like I said, if possible at all look into it. It is wonderful having intimate knowledge of every single nail screw socket window door corner and flooring that you put in yourself, PLUS you know it is going to be square!!!
