My tenants have left after 4 years. They were fantastic tenants. During their stay I increased the rent twice at 4% each time. I will now be advertising for new tenants and looking for any useful tips when advertising. I presume I can only increase the rent by 4% as it is 12 months since I last notified an increase. Does everyone charge a one month deposit or can one charge slightly more. Any particular guidelines I need to be aware of when advertising and seeking information from prospective tenants. Your help is appreciated.
