I am renting out rooms in a property. I am selling it and asked the Tenants if they would like to stay until June - students - as originally planned, or would they like to move out before that in April when college finishes. I agreed that I would not have viewings until they moved out. They agreed to stay, but then one week later stated they wanted to move out immediately, and requested full return of their deposit. They said that Threshold, said that there are no contractual obligations for licensee and that they are entitled to full return of deposit if the move out. This will leave me out of pocket as the bills are included in the rent. I offered half of the deposit to be returned as a goodwill gesture for moving out with one week's notice. The rent is paid monthly, and the original email to them when moving in was that the room was to be available to them until June. I agreed not to change this if they still wanted same. Where do I stand with this?
