Just tell your landlord to stick their rent increase next time. If they say no, leave. They will easily lose the 1200 in the month or months the house is vacant unless they can get someone in right away.

Unless you have very specific requirements, it’s very easy to find a new place. There are hundreds of landlords hoping to rent to you on craigslist every day. Landlords who get greedy on rents will find themselves with empty houses unless they can get timid tenants who bend over and take whatever is thrown at them.
