Alternatively, maybe a single-family neighborhood would make sense. 

I've already offered them cash/offered to pay moving expenses/searched for alternate housing for them (nothing is "good enough")/offered to pay for a storage unit for them.

That's a reasonable concern, but I explained that without poison the only alternative is the traps.

@Justin WrightIt seems like you are trying to get overly complex with the legal structure.Sometimes it is best to keep it simple.With that said you should definitely consult with an attorney and accountant before proceeding.You should be aware of the cost of the complex structure(upfront costs and annual) and then compare it with any alternative methods of asset protection(insurance).

If it doesn’t/can’t fuel your dreams as well as other properties can and you aren’t attached to it, by all means dump it.

Additionally, if your mortgage is not owned by Fannie Mae or Freddie Mac there are significant limitations to the CARES Act.  2008 was a nightmare and a lot of it was fueled by people following generalized information/advise provided by experts.  

Many investors have found success through investing in alternative assets with their self-directed IRA, including in real estate.

It's a bit overwhelming and I am worried that pursuing both strategies simultaneously will only fuel my analysis paralysis.

An alternative option that we use is to allow them to vacate, but require them to continue paying the rent and utilities.

I alternate between PC and letter.
