Yes, that sort of thing is why people hate landlords, because they will often throw people out with much less notice than they demand. And there's a significant difference between the sort of landlord that owns a few buildings and can be negotiated with directly, and big corporate landlords that exploit their strategic advantage.

That's because you're putting the landlord to a lot of unexpected effort and expense which he was expecting to amortize over the full term of the lease. Are you saying something similar applies here?
