We have a rental 3 year rental agreement. The managing agent just phoned that we were due for an increase between 3-7% in May but there was an oversight on their end. We had a verbal agreement to a fixed rent for 3 years and did not realise we signed the lease stating they were able to increase the rent. My question is when can they do the increase if it says annually and we are already 6 months into the second year or tenancy? Thanks for you help
