When skip tracing doesn't work

[Chris Gordon]

Found an obviously vacant house in a great part of town. Talked to the neighbor who confirmed it and that the owner moved out of state. County records show property is 3 years behind on taxes.

Use skipgenie and called every number listed. No answer, disconnected, was able to leave a single voicemail.

Anything else I can do short of door knocking his address 1000 miles away? Any success with contacting the individuals skip trace shows may be relatives?
