I feel the other reviews may be the same poster using different accounts...
However my fiance and I had a great experience from start to finish with keystone custom homes. Great communication with the advisors, design center, project manager and the warranty expert. Our house was completed on time with no corners cut, we visited the site daily and never saw anything shady. The upgrades we picked were fair and we saw no gimmicks with pricing.
Overall, was a pleasant experience and we have a wonderful home now. I highly recommend keystone to anyone looking to build a home!
