I am going to be selling my property which is currently let. I plan to talk to my tenants in a couple of weeks to see how they wish to proceed. I am happy for them to stay until sale or go if that's what they would prefer but I'd like to offer a rental discount either way for their inconvenience. They are on a rolling contract so I would have to give them 2 months notice and they would have to give me one month. What amount of discount would be appropriate? If they choose to leave I'd like to give them a discount to go towards moving cost, of they stay I'd like to give them a discount for inconvenience of allowing viewings as well as the above discount. Any thoughts?
