Common mistakes include ignoring the rent review notice, failing to check whether the required notice period and written details were provided, and not checking the applicable rent-increase rules for the property. Tenants should keep the notice, tenancy agreement and relevant emails, and raise concerns promptly rather than relying on verbal discussions alone. Do not simply stop paying rent, as this could create a separate arrears issue. If the dispute cannot be resolved with the landlord, the RTB can consider it through its dispute resolution process, based on the individual tenancy facts.
