The property I was renting was owned by the builder who has sold it to a housing association which is fine. The housing association is keeping the flats but wishes to sell the house I am in. They gave me the standard two months notice at the end of November but said we could stay until the house was sold. We are now a month passed the deadline for moving out and have had no viewings. Do the housing association have to re-issue a two month notice? If they do what is the legal authority on this?
