Being a happy homeowner has as much to do with choosing the right home as it does with choosing who builds it. After all, you'll live in your home for years to come, and it's likely the largest single investment you've ever made. So before you get into a long-term relationship with a homebuilder that you could have second thoughts about later, make sure you understand what is included in your homebuilder's warranty and, more importantly, how the warranty service is completed.
