So I’ll let you know what I know with the caveat that I’m not a lawyer, CPA, nor do I know your tax situation or how the syndications you are considering are structured.

I'm not a lawyer but I have to imagine you can get the tenants to sign a new lease now with your name and everything on it that is contingent upon this sale going through.

@Michael Meade,I may be the lone voice here (and I am in no way a lawyer or legal scholar, so take it for a grain of salt) I recommend getting qualified counsel in your area who specializes in Bankruptcy and landlord law. 

Not a lawyer, nor CPA, so take this with due diligence:1.

I am looking for recommendation for a good lawyer to set up an LLC  for a storage unit property that I am looking to purchase.

The lawyer should be able to advise you about the beat way to legally decline her.

Best case is that they just upgraded it and plan on leaving it...... if so, get that in writing.......but still be pissed and let them know this will not be tolerated again.So I would want some more info before I freak out too bad....If they are basically blowing you off and ignoring you, then I would move forward with legal action by consulting a lawyer about moving forward with an eviction...and be sure to include the cost of a new stove in the deposit

The lease could say that you can only conduct the business you tell them about (e.g. lawyer, accountant, consultant, sales, etc.). 

Another “BS thing” that may have gone away or may have been a Vegas only thing is a $5-$10,000 “negotiation fee” charged by a “lawyer” representing the seller.
