@KenMaxi I'm afraid those saves are pretty broken.When you choose load, nothing ever loads and resume does load the lot but then you get stuck again.
Disabling For Rent makes the game playable again. The families that live in the lot in San Myshuno do get evicted and just one remains but they do seem playable. I haven't tested for too long but maybe you can give it a try and play on a backup for a while to see if any further issues occur.
The penthouse lot does give me an error saying there's too many elevators.
Here's a tutorial on how to disable:
