I went to the builders site.
"At Rausch Coleman Homes, we honor God through our commitment to Integrity and Excellence in all aspects of homebuilding.
I also saw the models they build. Jill and Derick built the smallest(not small by any means)and cheapest according to their site. The site says that model starts at $918 a month, but that's before taxes and insurance. Of course this changes with whatever the interest rates are and if they put any money down.
Edited to add that the reviews for these builders and homes are awful. From what I've read, they fall apart after a few years and use cheap cheap materials. Someone said that the houses don't cost much because they pay the contractors low cost based on how many houses they can build in a subdivision.
Derick must've read the "God" part of their testimony and went with it. Investigating the builders, their work and reviews are step one in finding a decent builder...
