My husband does want to move too. Even though he's a patient NT with no hearing issues the noise above does get him down to a certain extent.Good. Happy to help.
Then it doesn't really matter whether a new landlord is also stinking rich and greedy. That won't be any worse than where you are.
This is also my experience of landlords - particularly the stinking rich and greedy ones. If you prove that you're a reliable tenant they actually want to keep you. That's why they would be lenient. By the way, unemployment is not grounds for eviction - as long as you can pay the rent, the landlord can't legally do anything just because you become unemployed.
Only you can decide with your husband about whether to move of course, but perhaps in this case it's better the devil you know.
If we didn't have to put up with precious little families living above then we would stay. If they lived below then the noises they make won't bug me so much. It's the fact that they're above that makes the sound travel in weirder ways. I'd love to know the science behind that.
I have asked my husband if we could do a swap with them upstairs, they can come down and we'll go up. But for some reason he doesn't like this idea. I'm sure they wouldn't mind, as it must be a struggle with getting the stroller up and down the stairs (not that they go out ever anyway but it's still not the point), and they'd be closer to the garden so that they can let the brat run around outside. I'd rather hear them outside than thundering about above. And then I might start to like them and not see them as elephants any more.
