I know it is a difficult task for someone without experience.

As far as the turnover I would fully agree but this is one of the unique things about this offering/location.

I've been doing these tasks myself up until now.  

I bring value to any relationship I begin due to my drive honesty and ability to complete tasks and I'm a networking powerhouse in my demographic area especially

Your first tasks will have nothing to do with real estate, they will be menial like getting coffee and running errands.   

Another possibility is if I purchase a second property and need that one managed, assuming my wife doesn’t want to take on that task.

Like others said, Zestimate can be wildly inaccurate, especially on a unique property or one that is especially dilapidated or upgraded.Instead of asking agents to comp it, pay a broker for a Broker Price Opinion (BPO).

Do not push off tasks that could be done sooner.

If you go it alone and submit notices incorrectly, or don't notify him in the correct way, or do any of the other number of tasks wrong you risk making it worse, potentially paying damages, and still having him living there. 

You won't keep your network of realtors if you aren't using them to close the deals they find for you.I have a unique realtor and I use her for every single purchase I make.
