Seems like you´re looking to for long term wealth building, thus Buy & Hold would be better suited for that goal.

The Silicon Valley effect essentially pushes long-time locals and general workers out of the market like a take-over. 

When someone is already on month-to-month, typically only 30 days notice is required to put new rental rates into effect.  

In the event of a big money suit that draws your insurance company in, think about how not re-keying gives your insurance an argument to not pay due to your lack of diligence in cutting off one option of potential harm to your tenant over which you have complete control. 

It is still the #1 best, cheapest, most effective strategy to simply negotiate and work with the tenants on a human level.

If not, what is an effective source that would enable me to take action?

@JD Martin I want to just make it a steady surcharge so it's effectively rent, that's what the monthly automatic payment will be.

I booked the Governor's suite and I'd be happy to host some social sit-downs with other conference members.

Would advise to proceed VERY cautiously with buying a Class D rental as your first investment.We like to think we do a pretty good job with Class C rentals, but we couldn't effectively manage Class D.The only investors we've seen "successful" with Class D are those that go by their rentals 3-4+ times/week.
