Do you have any suggestions that may suit my criteria a little more?

There is no class action suit at this point.

I am primarily hosting traveling medical personnel because there is a lot of demand for these professionals in our area and because my units are suited to their needs.

Once you've identified what's important and what ratios to look for to evaluate a property, all future deals should be weighted against those "good" ratios/numbers - and periodically adjust to suit your goals.

You might be able to have it considered as a mother in law suite.

I’ve seen cases where the lender filed the deed in lieu, then when the borrower threatened suit offered them a cash settlement to forgo litigation.  

We’re really best suited for those high income earners out there with strong investment experience and cash positions to literally take the reigns and create a strong cash flow product and tax write off for them with minimal time spent on their part.

The list of property management suites at Capterra is a decent start, so long as you take their reviews with a grain of salt. 

I think there is value in ADU as long as it is legally done and can be legally rented.On the sale side a benefit can always be an in law suite.

There are a lot of ways to crash and burn, so increasing the odds of succeeding long term should be your highest priority. you can always sell your local assets once you're comfortable managing rentals and ready for a market that better-suits your criteria. btw, kudos for being self-aware of your limitations.
