I have a nearly perfect credit score and I'm gambling on that for my first project.

However, that was long ago before the (internet) in a specialized environment.

Here are some methods I have used so far.Free Sources:- information, or free internet search like switchboard.com- pipl.com (not too bad for free - finds social networking sites too)- Courthouse records (shows previous subpoena addresses and if they have a driving offence their date of birth in my county.

(Cash flow is always a gamble.).

I wouldn't start on the Internet for that because people can be creepy.

This is a great place to learn, just like everything on the internet just do not believe everything you read and if it seems too good to be true it probably is. 

He only pays $325/month.For people interested in the numbers:Purchase Price: $250,000Rents when fully occupied are $5,500/month (most units rent for $175/week) My monthly expenses are roughly $2000/month (working on lowering this buy buying the Water softener isnt of rent, switching the internet/cable company, and adding insulation in roof to lower my utility bills)The best way to get started is to just get started, I dont have all the answers but it seemed like a good deal and a great learning experience! 

Overall I would treat this investment as a high risk gamble and willing to accept loss if it failed but It's also a very interesting process to understand how the industry works.

I own multiple properties over 2000 miles from my primary residence, but it's not as easy as strangers on the internet make it seem.

If after adding the additional monthly recurring costs (electricity, gas, water, internet, insurance, lawn care, snow plowing, etc.) to the standard long-term costs (Mortgage, taxes, regular insurance, etc.) the property won't net at least $100 if I can get the average rent I see on FF for that area, then the property isn't worth more investigation.
