We are not new to home construction. The home we built with Hiline took nearly 11 months after the contract was signed. They have a severe lack of project management and oversight. Had we not been able to be at the construction site every day, I'm not sure how long it would have taken to complete the home or what we would have ended up with.
Know and understand the contract you will be asked to sign. Every change order, no matter how small or large will cost you well above what you would pay outside of the contract.
If you are building one of their standard homes you may fare better than if you are building more of a custom home. If you are after a custom home. then find another builder. If this is the first time you are building a home, then find another builder. If you don't have the patience for excuses and lies, then find another builder.
