(and there are issues with agency here) her concessions may cause bad feelings when you have to tell the tenant she wasn't "authorized" to agree to something. 

A great mix of homes, and the Airport Transit Authority, TSA, etc.

@Marc Middleton I’m not sure of the specific procedures, but they’d have to show they were the owners or successors of the llc and I assume there is a procedure to regain authority to sell/manage the property.

He is not authorized to make improvements without your permission, which should be given in advance, in writing, and detailed enough to ensure there's no confusion about what's authorized, who's paying for it, how it will be done, when it will be done, and what happens with the improvement after termination.

The daughter will need legal authority to sell, which may mean opening probate.

I never hear of a law stating that a property owner or manager needs to give s notice stating that there is a change of who is managing the property, but it makes sense that a property owner or management company does give such a notice so the tenant knows who they are supposed to legally answer to and so the tenant knows who is authorized to enter their rental unit, but since you are the owner I don't think a 30-day notice should be required and a certified letter giving even only one day should suffice.As soon as we have any issues with a tenant that pertains to any type of entry problems, laws, lawsuit, or verbal argument we tell the tenant that all communications must be in writing whether through text messages, letters, or notes on toilet paper.In 2001, I made a promise to myself that I would never let a tenant get me emotional or upset and I have stuck with that promise.
