Well, the extreme case of non-upkeep is the vacant buildings in NYC, etc. When nobody can make a profit from a building, it gets abandoned. This isn't an overnight process. It starts by using a tarp on the roof instead of fixing the roof, and it ends when the building is abandoned and nobody has to pay any rent or fix any broken pipes, etc. I agree that the public would rather "force evil landlords to do x" than achieve the social goal in a minimally economically distortionary way. It similar to how politicians give handouts to people who drive hybrid cars while at the same time fighting a hugely expensive war to prevent oil prices from increasing to the point where people would just buy electric cars because they were cheaper!
