Hello, welcome to Justanswer.
My name is Tony and I shall help with your question.
Was the tenancy that you had an assured shorthold tenancy?
i think so
Did it start for 6 months?
no i think it was 12months
Okay - that's fine. It'll be an assured shorthold tenancy most likely that has now lapsed and which continues month to month under statute.
Basically, you can be removed from the property at any time following service of a notice under the Housing Act. This would have to be a 2 month notice.
There aren't really any defences to these notices, so unfortunately, you wouldn't have absolute security. What you could do, however, is seek an assurance from the new purchasers that they're not seeking to force you to leave when they acquire the property.
Unfortunately, though, there are no guarantees with this type of tenancy.
I'm sorry I appreciate this isn't what you wanted to hear, but it's important that I give you accurate information.
Is there anything you wish to ask me further about this?
Would you mind rating the answer for me please if you have no further questions for me?
