A relation has recently purchased a property. It was previously rented at a low rent. He has contacted the RTB to try to find out the date the previous tenant left. He intends to use the property for 18 months (at least). He enquired to the RTB and provided proof of ownership, ID etc on request. However the RTB will now not give out any information about the previous tenancy. When he first enquired he was given the impression that they would provide the date. How is he to know when he can re let and reset rent ?
