Do you have a lease? If not, he can raise it any amount he wants, and you can opt to leave (as you already said you are). If you have a lease, he can do nothing at all. If he tries to evict you, you will be out long before the eviction could take place, and it will cost HIM. Do not withhold rent. That puts you in a legal bind. You can tell him to apply the money he took as security when you signed the lease, to the last month’s rent.
