You can still make notes of the time/date/content of the calls, but it's rather pointless unless you are seriously going to report to the TRO or attempt a civil claim for damages for unlawful harassment. Frankly, the alleged 'harassment' is at a level highly unlikely to result in a criminal prosecution or more than a few quid in damages in the civil court.We really should of made a record of all phonecalls but have the latest email (which says, "further to our telephone call")and took a photo of shipping container outside.
Technically speaking, if you wish to unilaterally end the tenancy, you need to serve written notice to quit to end it. The notice must be at least one month long and also expire at the end of a tenancy period. For example, if you were to serve notice tomorrow, 8th Feb, then the earliest it could expire would be 20th March 2013.
Of course, the LL is desperate to move back in (seems unlikely he's seriously decided to sell), and I'm sure would be more than happy to agree to a surrender on whatever date you offer, so it's slightly beside the point but nevertheless something to bear in mind.
You could come unstuck if you get the LL to agree to pay you £X to move out next week, then your property purchase falls through as so often happens. If you're going to try to get a pay off to move out, then I'd only do so after you've exchanged contracts on the purchase.
But since it's likely you may be moving out in as little as four weeks, whatever you do, you can't simply close down contact with the LL.we ignored this request, and have not made further contact
