Most good contractors should have an instagram account with their work.

Particularly around advertising online on channels like Facebook, Instagram, Google Search,  YouTube, etc? 

Since you are looking for buyers I suggest joining as many networking sites as possible, Facebook, Instagram, and an app called meetup and focus on any groups involved in real estate, especially in your areas of interest. 

Somebody turn this into an Instagram quote, Make sure ya'll give me credit though lol

"Instagram model"...thats the first red flag.

Also spend a lot of time listening to podcasts while driving.I'm not on Facebook, Twitter, Instagram, etc and I dont listen to much music while driving I listen to bigger pockets and other podcasts instead.

Pay attention to how long you are on Facebook or Instagram.

Search them by email and phone number on Facebook/Instagram (some people have dual accounts attached to each).If they have a position that would require a work email you can run their name and company website through a tool such as hunter.io or voilanorbert.com and for a very small fee you can ping their servers to see if they have company email address.Simplest screening step was already mentioned... rent to income ratio.

By staying in front of them, you'll stay top of mind and brand yourself in the space.Have you considered other platforms like FaceBook and Instagram? 

Or are you scrolling through Instagram?
