The price of an average home increased by nearly £10,000 between April and May, the biggest month-on-month cash increase ever recorded. Figures from Rightmove, the property website, showed house prices jumped by nine per cent over the past year, pushing up the value of an average home to record levels. The news came as the Bank of England said that people could be stopped taking out mortgages worth many times their salary to buy new homes to cool the market. Asking prices for homes in England and Wales increased by 3.6 per cent or £9,409 outstripping the previous record of £8,310 in October 2012 between April 6 and May 10.
