Once they start to do the interior finish work you will want to go buy regularly once every few days or once a week is good) and take a look at things and make sure everything matches what you ordered and that it's not scratched or dented etc. Bear in mind most builders actually do want their clients to be happy, and most buyers have very little residential building experience. Often this lack of experience creates issues that really aren't necessary, things that you may think are "wrong" or 'strange" may in fact be standard building techniques or processes. Rather than immediately assume the worst, when you see something you don't understand or think is wrong, bring it to the attention of the builder and give them a chance to explain. If you're still not satisfied review it with your home inspector and ask their opinion.
The builder will be doing a walk through with you right before closing and will explain how things work, review the warranty program, etc. Pay attention, this is a great time to learn how your home works. After that enjoy your new home.
