My advice is to accept all forms of payment (maybe not bitcoin or 20 chickens - lol).As far as calling code enforcement well, all you can do, and should have been doing, is keeping your property up to code in the first place.

You won’t be able to keep a furnace or Ac unit in there learn from someone who has already been through it I inherited a rental there during the process of me obtaining it literally everything was stolen out of it.

The benefit of hiring an expert is that the credentials can be helpful in arbitration.If the property manager works for a management company, going through BBB can be one approach as well even though BBB is so and so in my opinion.Maybe also a small courts claim to avoid litigation expenses depending on amount that may have been stolen from you.PM me if you have any particular questions or would like to discuss in more detail.

Landlord shall notbe responsible for any of Tenant’s personal property that is lost, stolen, damaged or destroyed, regardless of the cause; Tenant hereby assumes the risk of all said losses”.This seems super suspicious.
