If the tenant terminates his rent, he only has to take the period of consideration in account. This period is usually one month, but this can also be extended by contract with a maximum of three months. If the rent is terminated you have to leave your room in the original state. Any changes or things can be sold to the new tenant. The landlord has to give you your deposit back, if you leave your room in good condition. If necessary, remind your landlord to this fact. It is probably the best for your own and landlords certainty to terminate your rent by registered letter with a signature return. It’s a special case if the room is rent for a minimum period. A lot of people see these contracts as a fixed-term contract. As a tenant, you are not obligated to leave your room after this period, but you can’t terminate your rent before the contract is ended with a maximum period of a year.
