Your question
What is the maximum the homeowner can raise the rent when contract gets renewed?
The supplied sources do not set a fixed maximum percentage or amount by which rent may be raised when a contract is renewed. A homeowner must apply for authorisation to increase the rent, and the rent board may authorise an amount it considers reasonable. 2 5
If a rent has been registered or determined by a rent board, the homeowner may not charge more than the authorised or determined amount. Charging more can constitute an offence and may require refunding the excess to the tenant. 1 3
