Send him an eviction letter for breaking the lease of non payment, if dont know what to do get a lawyer on it now.

My realtor disappeared for months without a single update, I had no ability to contact the seller or seller's agent, the lawyer (recommended by my realtor) wasn't returning my calls.

Often you or your representative can do the showings. 

Also if you are going to syndicate, do not use a 504 offering, even if the lawyer advises it.

Maybe have your lawyer try and find the seller's criminal defense attorney and pitch the idea of having them get the docs signed.

And if it does, lower prices might not represent a "deal" when adjusted for the reality of the fundamentals.

LLC can be taxed as a corporation if you have filed Form 8832 for the LLC, if that is the case, the LLC will be paying the taxes due and probably at a lower rate (but watch out for double taxation once at the LLC level and another at the personal level), that's my understanding, again best to speak to a good tax accountant or tax lawyer before making a decision.

You don’t want them saying ‘we weren’t notified’2) talk to a lawyer now.

Challenges included having multiple representatives not be able to positively confirm the smell for multiple months after hours of trying to replicate.
