I lived in a small cottage with a garage for 16 years and had made the garage a work shop. Hard to imagine how I could have gone from receiving a letter to living in a new home in just 30 days.
When I remember just being a guy in an apartment it took me about 2 days to move, even married in a 3 bedroom apt I was fine with a 30 day notice because my living was easily transferable from one apt. to the next.
When people shift to long term house living everything changes, after a very long period of living in a house, it takes a while to get your life and packing in order and find a new suitable dwelling and get everything relocated to that new dwelling.
To me this sounds like a balance could be worked out, such as starting the 60 day notice after 3 years for apts. and 18 months for houses, that would eliminate the worst of the problems.
I spent a few years in the apt. business in maintenance, then management, so I know full well the horror stories, and can tell you many.
Any improvements or changes you make to rental property you have to be willing to leave behind. That's the risk you take with renting.
I don't understand why a person would live in one place for 16 years without buying. It doesn't make sense.
