London's house prices are growing at the fastest pace since the late 1980s, according to property economist Matthew Pointon.
Mr Pointon, who works for Capital Economics, said mortgage approvals have now been falling for four months in a row.
He warned: "The risk of a damaging house price correction at some point in the next few years is growing."
Despite being at an all-time high experts predict a further four to five per cent rise in house prices by the end of 2014.
Howard Archer, chief UK and European economist for IHS Global Insight, said this could increase to seven per cent in 2015.
He said: "At the moment, house prices still look more likely than not to see clear increases over the coming months, although it is looking increasingly probable that there will be some easing back in house price gains from the recent very strong increases."
The gap in house prices in London and the rest of the UK is the widest it's ever been, reports ITV's Business Editor Joel Hills.
