You can usually find them on facebook or on meetup.com.I'd network like crazy and try to speak with existing landlords about where the best places are to invest in your area.

Apps such as 5mile and other online selling platforms such as facebook and other market places and BOOM it hit me.  

Are you a member of private neighborhood facebook group?

I wish there was a simple easy way I could tell you I figured out, but so far it's basically just combing through craigslist (after a while I've learned to tell which posts were just wholesalers and which were actual owners at a glance), consistent posting on facebook, calling off "for rent" signs, and a couple multi-family brokers I've bought lunch for (best investment yet!)

If you have any spare time give us a review on Yelp and or Facebook. 

I found some contradictions that I listed here on Facebook.

These families may be doing their research online allowing you to target them very precisely with Facebook and google ad words marketing. 

Go to a REIA meet up and check for Facebook groups.

Also lookup Facebook groups in your area.
