Potential "Subject To" Next door

[Spenser Harding]

Need some help. I moved into my house October 2012 and the neighbor next door bought his house about 3 months before that. He is an interesting character who never mows his lawn, infact, he moved a wheelbarrow into his back yard in January and it is now lost amongst the grass. My question is, he left suddenly with all his belongings and cars about two weeks ago. I don't know his name, where he works, or anything. The house is vacant (in bad shape), I see investment opportunity here but am not certain on the best path to take. I listened to the most recent podcast today and it focused on "Subject To" but don't know if this scenario might be the best fit or not. I don't know how to get ahold of the guy to figure out his situation. How can I go about doing find his info via public sources and what would be the best investment strategy here?
