People in C and D class will tell the tenants to use their insurance and kick rocks.

Does anyone have a rockstar title company that accepts the challenges of working with wholesalers?

She's a rockstar.

Some things I do to avoid bad situations: screen well, only have properties in good locations where people actually want to live (I find tenants behave better when they know they have a good thing going for them and that they are easily replaceable), set proper expectations, have a rock solid lease, go over it with new tenants to make sure everything is clear and agreed upon, and enforce the lease by issuing a formal notice to pay or quit every single time rent is late by even one day (and charge the late fee), or a formal notice to cure or quit every time there is a lease violation.

He is a rockstar realtor in Maricopa county helping lots of investors and house hackers.

And have them draft you a rock solid contract that protects your future interests in situations like this in the future.

My wife's parents live in Castle Rock (1.5 hours away). 

There is a reason Black Rock has an entire division dedicated to just selling C4D. 

Your next real estate competition might not be Black Rock or Bezos...it could be coming from the family of the friends you grew up with.
