Is it correct that whenever the rate of rent is altered, a fresh tenancy comes into being ? If a landlord accepts enhanced rent during the period of the tenancy, does the earlier tenancy comes to an end and a new tenancy begins. What does law say on this ?
Yes correct, whenever the rate is altered a new tenancy begins. If you are a tenant at will or sufferage (month - month basically) the landlord must provide a 30 day written notice of the rate change. you don't have to accept as long as you continue to pay the old rate. The landlord may still evict you however it would not be a non payment eviction but rather a no fault eviction.
