Since the introduction of the Landlord and Tenant (Ground Rent) (No. 2) Act, 1978, all sales of local authority houses, under the tenant purchase scheme, are on the basis of fee simple rather than on a leasehold arrangement which previously applied. It is a matter for the relevant local authority, which is responsible for the administration of the tenant purchase scheme, to acquire the ground rent speedily to enable the sale in fee simple to proceed. However, I understand that in a minority of cases, legal difficulties can delay finalisation of the process, particularly where title proves hard to establish. Having said that, I would point out that pending finalisation of the sale, the purchase price quoted by the authority to the tenant is frozen.
