In the light of representations that the financial wellbeing of individual housing associations could be adversely affected if their existing assured tenants were all given the right to buy at once (the "big bang" approach), we are considering whether, and if so in what precise financial circumstances, housing associations might be given the ability to opt out of the right to buy element of the single social tenancy for a specified period, in respect of properties occupied by assured tenants who do not have the right to buy.We are also continuing with consultations on further exemptions from the right to buy for houses built for persons with special needs.
