It is always more expensive than anticipitated!
Foundation = $25,000
House = $120,000
Oil Furnace/A.C. = $10,000
Plumbing = $2,800
Electric = $500?? (this bill hasn't come in yet).
These are just approximate numbers. The total project cost is about $160,000. We planned on doing the plumbing/heating and electrical our self, but the bank would not let us.
Luckily, we have a septic system and utilities (elec, water, phone) already on site. If I didn't have those it would be another $10,000 to $15,000 easy.
As for the house mfg being close, I don't know that it was really a big difference to us. I am sure it was cheaper, but probably only by hundreds of dollars not thousands.
I know the different mfg's are only allowed to sell to certain states or areas, but I am not sure how that is regulated or anything.
