Can a landlorad raise my rent middle of lease

Julie, A lease is a contract, the contract is formed so that both parties to the contract know what to expect from the other for the defined time of the contract.  Renters enter into leases so that they know that they will have a home for the next 12 months and so that they know that their monthly rent will not be increased for the next 12 months.  Lessors enter into lease so that they know that their home will be occupied for the next 12 months and they know that the rent they receive cannot  be less than the contracted rate. Your landlord cannot raise your monthly rent during the course of a valid lease.  You should not pay the increased rent and they cannot evict you for not paying it, so long as you have not otherwise agreed to modify the contract.
