The biggest question for me is how much are you going to automate it.

Generally, the recorded instrument that places the lien for the cross is in first position, so other liens will have to be subordinated to it.

This may be an attractive to your tenants.If you search automated rental payments here, you will find threads which mention these and other services available.  

Systems to send delinquent tenants three day notices and evictions in an automated fashion.

ACCEPTANCE: This instrument will become a binding contract when accepted by the Seller and signed by both Buyer and Seller.

As others said earlier in this thread, getting a random text from an investor is not likely to get things off on the right foot anyway.Emails: The least regulated of the three, as long as your email templates include address, opt out, and other rules, you can fire away.Almost all regulations allow any kind of automated communication as long as the seller has reached out to you first or recently.Always maintain a posture of being "the guy down the street" flipping houses or whatever. 

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

If watering is required, I would automate that with timers and a sprinkler system.

But there is a lot of room to automate operations as most owners are mom and pops (i.e. super inefficient).

Aside from having your properties shown and having a relationship with a good handyman,  automating other processes like collecting rent would make your job easier to self-manage your properties from a distance.
