Personally I think it'd be a smart idea to bake some sort of clause into a house hacking lease that removes Landlord of such liability and asserts Tenants are aware of and assume the risk of covid-19 transmission in such a co-living arrangement.

I figure if you want to make an assertion, you will.

I will stick by my earlier assertion that you're buying into a problem.

I have a feeling it's much like good classroom management: set expectations early, provide limits/boundaries, assert and enforce consequences like who pays for what.  

Everything else, from her disability to her excuses is asserted.  

the fastest date I can legally have her out.Inform her (in writing) of this move-out date and offer to pay her $XXX to be gone on or before then.Prepare a simple one-page Lease Termination Agreement to be signed by tenant indicating she has voluntarily moved out in exchange for $XXX in compensation, further asserting she is terminating her month-to-month lease, has returned all keys, and will not be reentering the premises, upon pain of committing trespass.Have tenant bring keys to attorney's office, sign/date/notarize the Agreement, and receive her $XXX in certified funds.The minute the tenant is done signing at the attorney's office, I'd be changing the locks.Good luck!

Tenant Assertions (when a tenant sues a PM/Landlord) are to be expected for anyone doing any volume of business. 

Thank you for the correction.But, it sounds as if we're in agreement that your assertion that you need MLS access but you don't need your license makes no sense in many states.

In a nutshell, the SEC’s Complaint asserts that from 2005 through September 2006, the Defendants were involved in one or more fraudulent investment offerings that purportedly involved real estate partnerships (“the Pinnacle Investment Program”).

I forgot I had even posted on this thread, but I still stand by my assertion that the late fee should go to the landlord, though I would make an allowance for specific extra collection efforts as @Steve Vaughan mentioned.
