My wife and I are going to be building on our acreage this year. We have three young children and I work very long hours so we have chosen to use a contractor to build our home for us. We already have our house plans completed. Our home will be a very simple, x2 story farm house. The main floor sq. footage is 720. The total sq. footage is roughly 1560, including a main floor bump out "mud room". As construction/material costs are always changing, I was wondering what a reasonable cost per square footage price would be to have a contractor build our home for us. We live in WA state. I know that there are lots of variables, but we're just looking for a ballpark figure from anyone with home building/construction experience, as it relates to cost per square footage. The house will not have a basement (High water table) so it's foundation will either be a slab on grade, or a stem wall w/ crawl space. Any sort of input would be greatly appreciated!
