Our proposals as set out in the Consultation Paper, Better Homes for Scotland's Communities: The Executive's Proposals for the Housing Bill envisage that it will be for housing associations themselves to decide, over the 10 year period, if and when to offer their tenants the modernised right to buy and that once a decision to "opt in" had been made, the modernised right to buy would continue to be available for the remainder of the 10 year period.
