David Cameron has dismissed fears that the Government is pumping up a housing bubble as he hailed the success of the Help to Buy scheme.
The Prime Minister branded sceptics of the mortgage guarantees - such as Liberal Democrat business secretary Vince Cable - “London-centric”.
In many parts of the country prices were “barely moving at all”, he insisted.
More than 6,000 people have put offers in on homes and applied for mortgages using Help to Buy since it was launched about three months ago.
Nearly 750 homeowners have completed their purchases and hundreds were able to spend Christmas in their new homes, according to the Government.
Mr Cameron said the initiative meant people without wealthy parents and a big deposit could “realise their dream” of owning a home, and he rejected concerns that high demand was already overheating the market.
“Where we are today, house prices are still way below the peak they reached in 2007,” he said.
“Forecasters do not think they will get back to the level before the crash even in 2019. So there is no evidence of a problem.
“This is about helping people to achieve the security and stability they want of owning a flat or a home of their own.
“We are not helping people to buy flats or homes they cannot afford.
“We are helping people who do not have wealthy parents, who cannot get a big deposit together, and helping them to realise their dreams.”
He added: “I think if you look across the country, there are many parts of the country where house prices are barely moving at all.
“Nationally, excluding London and the South East, house prices are up just 3% over the last year.
“I think there are some people who are rather London-centric about this.”
In November, ministers published figures showing that in the first month after being launched more than 2,000 people had put in offers on homes and applied for a Help to Buy mortgage. That number has now trebled.
The mortgages, once approved, would represent nearly £1 billion of new lending to aspiring home owners who may have previously found the property market out-of-reach because of the size of deposit required.
Barclays and Santander will introduce their own Help to Buy products on to the market this month, joining Lloyds Banking Group, RBS, HSBC, Virgin Money and Aldermore who have all launched products over the last three months. The expansion will mean two thirds of the entire UK mortgage market will offer products under the Help to Buy scheme, bringing home ownership to a growing number of people.
New figures also show that an additional 20,000 households have also been supported by the Help to Buy Equity Loan scheme, a separate scheme where the Government provides an interest-free loan to support the purchase of the newly built home. House building is now growing at its fastest rate since 2008, and is seen as a critical part of the country’s economic recovery.
