Safest way to remove residential rentals

Yes, I’m afraid to download rental lots after getting a while screen after testing rentals in a practice save.  That was a few months back, and it was in San Sequoia that they say they have fixed with the last patch.  I too am afraid to download anymore residential rentals, , or even make them, especially if I’m not sure I want that lot to always stay a residential rental.  My older daughter who is on a PlayStation ( I’m on a PC ) thinks the problem might be in the lot traits for the residential rentals since each rental can have different ones, she thinks when you get rid of a rental you need to first take off all the lot traits for each rental before changing it back to a residential.  I have not tested that theory out.  I made a couple of my own residential rentals that seem to work fine, and have a couple that I did download from the gallery, but I will probably never change those lots to anything other than residential Rental, at least until the sims team feel like they have completely fixed it.,   I give very serious thought before making any lot a residential rental.
