They're usually well meaning, but when they get involved with the leasing process, a repair issue, a neighbor complaint, etc,  it always escalates the issue.

What would you recommend to someone who wants to get involved? 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Be sure to tell your accountant that you may now need to file non-resident income tax returns in each state where you own property as well.

If we let 30 RVs on the property it may attract too much attention, but being conscious of neighbors the rural area takes on more of a 'ask for forgiveness rather than permission' vibe for anything that doesn't involve permanent structures.   

If I wanted to be more involved I may have considered starting a real estate biz like wholesaling, flipping, property management, etc.So, I would first determine how much time you want to 'invest' along side that $200k. 

Renewal shouldn't involve the agent.

Having an expert landlord attorney involved will help you a lot.As for the actual question, it is very difficult if not impossible to "stop" a tenant from damaging your property, because you are not inside the property to know what they are doing.

@Johnny SmithThere are other ways to reduce your taxes besides real estate.I recommend finding a tax strategist who specializes in real estate taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

Does anyone have any good recommendations on books or accounts I can follow or read to learn more? 

You can basic info on short term rental projections and occupancy rates with a free account, but will have to purchase a membership to get detailed info.
