I'm a landlord in a rent controlled city in NJ. My tenant's lease is up on 6/30/13 and renews on a month to month basis. In my lease it states that I may notify them of any proposed lease changes or increase atleast 60 days prior to the end of the lease. I am currently past that date. Can I still give then a notice that I am ending the prior lease and increasing the rent (amount given by the city) sixty days from the end of the lease? So their rent would increase as of 8/1/13. Is that okay? If it is okay, and they decide not to pay the increase, do they have to move out?
