It probably depends on your location.
Where I live, you can only (legally) increase rent by something like 4% per year. But if the price increase is within the legal limit, and the tenant doesn't want to (or can't) pay the new price, they either willingly move or are forcibly removed from the premises when they don't pay.
What does "clean FB account" mean? I'm assuming it's referencing Facebook account, but what is different with a "clean" account, as opposed to one you just create your self?
