@Cody DoverI think most would agree that apartment deals are tougher from an automation perspective.

Assuming one day you’d like the services of a wholesaler, would you prefer a call, automated voicemail, post card, email, or what?

Are you looking for an out of the box solution and alright with not having fine tune control over the automation or are you looking for something that would require more up front work that would allow you to modify to your liking? 

I am not familiar with Texas laws, but I would use two instruments here in California to accomplish your goals.     

The ones who express interest but not quite ready, we capture their email address and now they're thrown into a funnel with automated marketing messages with copy tailored fit.

Requisites of instruments other than deeds.

Mainly, the systems implemented are fascinating (VA, automated offers, etc.)

And my model is fairly automated.  

(Creepy seller has video cameras, “what do you want” automated Voice recording by front door, TV on all the time even if nobody home.)

As for my day job, I work in the cloud IT automation workspace.
