Maggies ruling that councils could use the cash from sale of their housing stock for purposes other than replacing the homes that they sold was the prime reason that councils sold of their entire housing stock to housing associations as mine did . The rules on purchase of housing association houses are much more stringent.
People such as me who were secure tenants of the council before the house was sold to a housing association have a retained right to buy.
This means I can buy my house from the housing association at the same discount that applies to a council house, around £90,000 discount at present. I can also pass on my tenancy to a child or grandchild, so I can pass on a secure tenancy and right to buy to my son.
