What skip tracing software is best for the scenario described?

[Shane Bowling]

I'm just looking for low hanging fruit in blighted neighborhoods and would like some opinions. I am just using my car as a mobile office and I come upon an abandoned home that might be a good candidate to make habitable. I want to type in the basic information available through public records and have some kind of chance that I will get a phone number or email that I can use right then to possibly contact the owner about their abandoned property. I typically have a phone, iPad, and computer with me. What tool do you think would work best in this scenario and what do you think it costs? I do not want to use the ones that require offices and locks, etc. Am very interested to see what people think. Thanks
