6/12 month lease vs Periodic

My lease is ending and the REA is trying to get me to sign another 12 months lease. I’ve been staying for two years now and they keep wanting to increase the rent every year due to “market evaluation” despite being a good tenant that pays rent on time, take care of the property and never causing issues. I’m thinking of not signing the lease and just go with a month to month agreement. I guess the downside to this is that the landlord can force me to vacate at anytime? How likely is this? Any other downside to a periodic agreement?
