Tenants mounting Large TVs on wall

[Mary M.]

Hello  BP - I am curious what other owners and PMs are doing/feeling about tenants mounting large, heavy, TVs on walls.....  I have had walls with 10+  3/4" holes with and without molly brackets still protruding (I guess they were hunting for a stud??)....    

How are folks handing these types of things?   Do you insist that your handyman install TVs?   Are you worried about a wall being Swiss cheese after several tenants? 

Allowing/disallowing?  weight restrictions?  I am really looking for hive mind guidance. TIA! 

ETA: I can repair the holes, I am more looking for how other folks handle requests or allowing TVs on walls
