It is crucially important that the banks don't throw petrol on the fire. Most of us who have been through various housing booms in the past have recognised that a kind of stable level is three or three-and-a-half times
I was appalled when I discovered that banks were lending five times.
They have already reined it back on advice from the Bank of England but this is the key area that the Bank of England has got to operate in to make sure that this boom in house prices, particularly in the south of England, doesn't destabilise the whole of the economy.
Business Secretary, Vince Cable, says he is appalled about the size of some loans being agreed by some lenders and has urged the Bank of England to use its powers to intervene.
Vince Cable renewed his stark warnings about the threat to the wider economy posed by soaring house prices in London and the south east amid reports Chancellor George Osborne will tackle the issue in his annual Mansion House speech later.
London Mayor Boris Johnson is due to launch his new London Rental Standard scheme today. The initiative is aimed at setting standards for renting in the capital by giving out a badge of accreditation given to landlords aimed so renters can choose more wisely.

Price increases have been quickening as the economic recovery has taken hold, with stronger demand leading to a surge in values.
A new survey has found that Londoners see the greatest need for house building in the UK.
68% agree that more new homes are required - a higher proportion than the national average of 56% and those in the North where only 52% agreed.

A quarter of all properties in London are now worth over £500,000, compared to one in seven in 2007, according to new figures.
Building society Nationwide, who released the report, said prices in the capital were being forced up by wealthy overseas investors buying up properties at the higher end of the market.
