driving for dollars and vacant homes

[Josue Rivera]

hey everyone hope all is well. I am fairly new to the investing world and real estate currently working on my first flip and getting closer to finishing that project and hopefully selling it fast. in the meanwhile i would like to fill my funnel and get ready to do my next deal/flip based on the type of work i do i drive a lot all over town "essentially driving for dollars" i started to write down address of vacant/distress homes which may have potential for rehabbing and selling them. My question now that I have the address what's the next step , How do i track down the owner and get in  contact with them (not afraid of calling them if i can get their number and talking to them on the phone),   or their current address were i can be able to send them my information and show my interest of buying their home.   

any information or advise will be greatly appreciated. Thank you
