Tenants facing annual rent increases from landlords, especially government corporations, should check their rental agreements. If the agreement doesn't permit such hikes, tenants can refuse the increase and seek a court injunction. Landlords generally cannot arbitrarily increase rent by 10% yearly; increases must either be in line with the agreement or mutually consented to by the tenant. If the landlord breaches the agreement, tenants should issue a legal notice and consider depositing rent into their bank account.
