SW postcodes hold 13 of the top 20 places in the table.
Wandsworth properties have the highest mortgage debt in the country with over £649 million collectively owed, according to a new report.
SW postcodes hold 13 of the top 20 places in the table compiled by the Council of Mortgage Lenders (CML) and British Bankers’ Association (BBA) which for the first time breaks down lending to postcode level.
Kingston upon Thames addresses are also represented three times on the list which shows that the capital has £227 billion owed on homes.
BBA Chief Executive Anthony Browne said the report makes the British financial services industry significantly more transparent.
The release of the figures comes after the CML reported earlier in the week that there were 26,800 loans to first-time buyers in October, a rise of 33% from the same time last year and the highest number since November 2007.
The Office for National Statistics also released figures this week which showed London house prices had risen 12% over the year, more than double the 5.5% average across the whole of the UK.
Prices paid by first-time buyers were 5.9% higher in October 2013 than October 2012, and 5.53% higher for existing home-owners.
The Bank of England, concerned about a new housing bubble, last month ended its Funding for Lending scheme for mortgages.
Governor of the bank Mark Carney, speaking at the Economic Club of New York, said: “There is a history in the housing market of moving from stall speed to warp speed. We want to avoid that.”
Concerns over an unchecked housing boom are connected to the government’s Help To Buy policy.
In the past week, Aldermore Bank (which was formed in 2009) launched the first Help To Buy mortgage guarantee on remortgages as well as new home purchases.
According to a government release last month, more than 2,000 people have put in offers under the scheme, totalling £365m of mortgage lending.
But in a Freedom of Information response to Labour’s Shadow Local Government Secretary Hilary Benn, officials admitted that publication of a government risk assessment for Help To Buy had been vetoed by ministers.
On Monday, Ed Miliband announced a new Labour housing commission which will be run by former chairman of the BBC Trust, Sir Michael Lyons.
