During the downturn, this was a viable investing model. 

To piggy back what @Hai Loc was saying, another way to look at the deal is look at it as an Airbnb model if your location allows you.

A few hundred bucks is a small investment in your investment, and making the trip will allow you to see some of their handiwork, tour neighborhoods, and get a feel for who these people are that will be responsible for making your investment a success.If you have any questions about the turnkey model or the Birmingham, AL market, feel free to reach out any time.Good luck!
