The attitude towards tenants on this thread by some is quite sad.
I rent because I'm a single parent and a teacher. I was financially shafted by my ex husband and have been unable to recover from that.
I've lived in my current home for 14 years. Whilst the LL has always sent a plumber etc round when I've called re an issue, she has never made good on any of the damage that problems have caused and issues that have not risked structural damage to the property haven't been addressed - damaged kitchen cabinets from leak, a hole in the ceiling...
In that time, I've redecorated the house twice to a higher standard than it was when I moved in and made countless little minor repairs along the way. When moved in, she told me to treat it as though it were mine - no restrictions on hanging pictures, decorating, pets etc. And I have. In every sense.
She now wants to sell and came to do an inspection a couple of weeks ago prior to having EAs round to value the place. It's the first time she has stepped foot inside the house in 10 years!
First off, she wasn't aware of the law and only issued a 2 month notice from 1st Sept. I responded to that and she issued the 6 month notice (from 1st Oct) but expects it to be only 5 months in reality because she didn't realise the 6 month notice period was to take effect from the newly reissued notice date rather than just extending the first notice date.
I'l be happy to leave tbh. There's a lot that needs doing to a house over 14 years and none of it has been done. I've kept it in a good state of repair/decoration - you wouldn't identify it on my very nice street as a tenanted house. And I'm hoping that i have found somewhere - just waiting for the Letting Agent to give the go ahead. As such, I haven't pointed out her error in the notice period because, hopefully, it will he irrelevant but, if this house falls through for any reason, I'll have no choice but to exercise my rights as a tenant.
I'm not a dick and I understand why she needs to sell and have sympathy for that. But I'm not living here as a favour to her and if i am unable to move expediently, then I will act within the law. As always.
Not sure why some people think that makes me scum or a squatter...
Having said all that, OP, i feel for you but you do sound as though you have tried (and are still trying) to be 'very nice' about it all.
Your answers to questions about notices, solicitors etc have been quite vague and that is why you are getting lots of, probably not very helpful, advice. People are having to try and make sense of the situation and piece it together with many gaps that leave a lot of it open to interpretation and misunderstandings.
It sounds to me that you have been somewhat duped by all sides. You've taken things at face value when you should have been asking tougher questions and setting out tougher boundaries for yourself. But the tenants are bit at fault in any way.
Even the whole nonsense of the LL asking them to.leave in December but only issuing a S21 two weeks ago. They have absolutely no obligation to move out before S21 (or similar) has been issued and the LL should have known that. Even then, S21 is the start if the process. Not the process in its entirety.
They are entitled by law (so not squatters) to remain in the property until the moment the bailiffs arrive to evict them. They also have a legal responsibility to continue paying rent during this time. The court process was put on hold last year and, when I spoke with Shelter to clarify the legal position in my own situation, I was advised that I'd be unlikely to have to move out for around a year after the S21 notice expired as a result. You could be in for a long wait!
