Landlord wants to sell

Hi All,

Our landlord sent my wife a message this morning basically saying that he wants to sell the property, we have a call with him on Sunday to discuss this a bit more and find out what's going on.

Am I correct that because he's told us today (6th May) that he must give us 4 months notice?

Never been in this situation before so quite stressed and anxious by it all. Any advice for when we chat with him on Sunday?

Thanks in advance.
