The Programme for Government ‘Our Shared Future’ includes a commitment to "retain and expand the Help to Buy scheme for new properties and self-build properties". The intention is to deliver on this and other commitments in the programme within the duration of the life of the Government.
In relation to the 70% loan to value floor in the scheme, I should also point out that one of the central policy aims of the Help to Buy scheme is to help make mortgages more accessible to first-time buyers, many of whom have difficulty securing the required deposit under the Central Bank macro-prudential rules. Individuals who are in the fortunate position of being able to avail of a mortgage at a lower loan-to-value ratio than 70% are considered to have sufficient resources to more than meet the deposit requirements of the macro-prudential rules and thus may be less in need of assistance from the Exchequer.
