Here's a good formula you can use to estimate costs and see where you can budget to save money. This was a 2500sq ft 3 bed 3 bath home with a 4 car garage all brick. Granite, travertine, engineered wood, on sight built cabinets, etc.
I sure hope those are nice light fixtures
I think the copy and paste button got stuck on $4100
Pretty sure it's just an overall budget to go by and if you were building it yourself. $82/ft is pretty cheap for most builders around here. I know many, but don't know one that would touch it for that.
