A scheme to help thousands of people buy their own home will be launched next week - three months earlier than planned.
The scheme was due to start in January 2014 but the government has announced that people will be able to start applying for the new mortgage guarantee from next week.
Several high street banks will be offering the new Help to Buy mortgages to customers, ranging from 80 to 95 per cent of the propertys value.
The mortgages backed by the government - will help thousands of people buy new or existing homes up to a maximum value of 600,000.
It is aimed at people who cannot get on the property ladder or move to a new home because they cannot afford the large deposit required, often up to 20 per cent.
Under the new mortgage guarantee scheme, the buyer would only need a 5 per cent deposit.
The government and the bank then jointly guarantees up to the next 15 per cent of the propertys value, in return for a fee paid for by the lender.
To be able to offer the guarantees ahead of schedule, the government will be allowing lenders to start writing loans that will become part of the scheme once it opens in January.
Because lenders know that they will be able to purchase a guarantee on these loans when the scheme opens in January, it means that they are able to offer high loan to value mortgages, much sooner.
Only repayment mortgages will be offered under the scheme.
There will be tough checks to make sure buyers can afford their mortgage payments and the borrowers income will be verified.
The scheme will not include interest-only or self-certified mortgages.
The new mortgages will not be available to people with a history of difficulties making debt repayments.
Official statistics show that mortgage lending is around half the level it was before the economic crisis, even though mortgage rates are at their lowest for five years.
Announced by the Chancellor at Budget 2013, the Help to Buy scheme has two parts, equity loan and mortgage guarantee.
Under the equity loan scheme, the government provides a loan of up to 20% of the value of a new build home, interest free for the first five years.
The Help to Buy: mortgage guarantee scheme will be available for three years up to January 2017. Every September the government and the Bank of England Financial Policy Committee will review the impact of the scheme and examine whether the fees or the price cap should be adjusted. If any future government proposed to extend the scheme beyond its three year life the FPC would need to agree.
