The bad ones will just set an automated search for you and rely on you to pick out the deals.

I'd like to automate everything with it and keep it hands off for the most part.

I think automation of home building technology (many off-site 3D printing players, some on site automation tech for construction of tract homes) will be a real factor in the next 3 to 10 years that will be the primary/only saving grace to actually make housing more affordable (easiest way to meaningfully decrease build costs).

The manufacturing companies that do have direct employees are almost fully automated and only have about 80 employees at each. 

Make the schedule and steps so simple, direct, straightforward, and automated that a 12 year old could easily run your management system. 

I think the comps are automated, similar to zillow.

I'm finally taking the plunge and setting up an automated voicemail so sellers can leave messages.I need a script so I can get a pretty girl to record it on the system.Does anyone have good scripts they would like to share?

You need an automated process to sort on the APN or the physical address and then delete the dups.

Homepath uses an automated system.  

As for time, you will spend some time getting setup, but if you use a mgmt platform (e.g. iGMS, OwnerRez, others) you can automate a lot of the process.
