I have driven by apt houses that have a line of dishes across the front of the house. If I were landlord, I wouldnt like it. Actually, putting in the lease "cable only, no rooftop dishes" is a good idea to put in for the landlord. My BFF has several rental properties, when I speak to her later, I will ask her what she does (I dont think she allows them)
We had one, dumped the service and the dish is still up there, I guess DH left it there " in case we get it again"...I think he does not wish to climb a 40 ft ladder and take it down

...I am in a permanent homeowner situation and I dont like the look of the dish (ine is behind the peak of the roof ) so I think I would like it less on a rental property I owned.
My BFF has so many troubles with tenants doing little things that cost her a fortune to fix when the time comes, that I am really turned off of having rental properties...She most recently had someone break into a vacant apt and squat there for a few days, making a little homeless nest for himself (her houses are all in good neiighborhoods, neighbors reported to the police ), and another tenant's adult son burned the kitchen down frying chicken wings.
