Help to Buy is a targeted scheme designed to help people who aspire to own a home. By increasing mortgage availability it will support the construction of new homes and help to boost the economy.
All mortgages sold under Help to Buy will have to meet clear criteria that ensure responsible borrowing. Nobody wants to see a return to the bad old days of 125% mortgages.
The intention of Help to Buy is absolutely clear - it is for people who want to own their first home or move to a bigger home, not a second home. We're working with the industry on the details of the scheme to do just that.
The Treasury committee has criticised several areas of the Chancellor's Right to Buy plans in a report on his latest Budget.
The intervention in the housing market may not even help first time buyers - the group the Government insists it is keen to support, MPs said.
They also said Mr Osborne's claim that increased demand will boost supply is "unconvincing".
MPs added that they "struggle to see the rationale for the taxpayer to stand behind loans for people wishing to own a second property".
The committee also warned the Government will come under "immense" pressure to extend Help to Buy in three years time, despite its status as "a scheme designed to deal with a supposedly temporary problem".
Help to Buy consists of two elements, an "equity loan" scheme and the mortgage guarantee.
Under the equity loan new or existing homeowners will need to raise a deposit of 5% of the value of the property they want to buy, but can borrow up to a further 20% from the Government on an interest-free basis. The biggest loan available will be £120,000.
The mortgage guarantee element will be available for all types of housing stock worth up to £600,000 from January. The Government will guarantee up to 15% of a mortgage, allowing people with 5% deposits access to lending.
George Osborne risks skewing the housing market at a huge cost to the Treasury with plans to boost home ownership through mortgage guarantees, a powerful committee of MPs has warned.
The Treasury committee warned the Chancellor's Help to Buy scheme is "very much work in progress" and may propel the Government as an active player in the market with a financial interest in maintaining house prices.
MPs warned a lenders fee structure the Government intends to put in place to cover the scheme's costs will be "extremely difficult" to price in a way that "sharply curtails Exchequer risk".
Housing minister Grant Shapps says the Right to Buy scheme will tackle housing waiting lists, as well as helping people meet their dreams of owning their own home.
Dagenham residents have given ITV News their views on the Government's Right to Buy scheme, which is being re-launched.
Concern has been raised that the Right to Buy scheme could lead to a shortage in affordable housing available to rent.
Campbell Robb, the chief executive of the housing charity Shelter, told The Independent that if the homes sold aren't replaced like for like, and landlords charge up to 80 per cent of market rents, the bulk of this "affordable" housing will still be far beyond the reach of many people.
"At a time when we already have a critical shortage of affordable housing in this country, this amounts to little more than asset-stripping and will ultimately mean fewer genuinely affordable homes for families struggling on low incomes," he said.
David Cameron says an increase in the discount available to tenants buying council homes will restore "a vital rung on the property ladder".Read the full story ›
