As Jason said, it could have been a model home or sometimes the builders live in a home in the development while they are building. Once the construction of the neighborhood is complete, they sell their home and move onto the next location.
There are many potential reasons. If you are interested in the house, I'd be happy to find out more information for you. I am available 8am-8pm daily. Feel free to give me a call or email to let me know your specific questions. If I can't answer them, I'd be happy to find the right answers for you.
