A valid rent review notice must include a statement by the landlord that it is their opinion that the new rent is not greater than market rent having regard to the other terms of the tenancy, letting values of dwellings of a similar size, type and character and situated in a comparable area.
It must include the rent amount for three comparable dwellings of a similar size, type and character and situated in a comparable area to establish market rent. It is important to note that a comparable area does not have to be in the same locality but can be in a different location e.g. a 3 bed property in one rural town can be compared with a 3 bed property in another rural town.
Evidence of the rent charged for comparable properties can be in the form of advertisements for such properties published within the previous four weeks. If a tenant considers that they are being asked to pay more than the market rent, they can seek clarification from the landlord or take a dispute case to the RTB within 28 days of receipt of receiving notice of the increase or before the increase takes effect.
