Extract: UK enjoys property sales boom amid Covid-19 pandemic Hard-to-sell homes are being snapped up by the hundred as Britain's booming property market maintains a year-long breakneck sales record. In areas of high demand, even the most knocked-about and idiosyncratic houses are spending just days on the market once buyers, desperate to grab something, see that predictions of a house price crash are proving off the mark. "Homes that look like the last turkey in the Christmas shop window are flying off the shelves at the moment," said property agent Henry Pryor. Andrew Wishart, property economist at consultants Capital Economics, said: "With the amount of secondhand stock on the market currently extremely limited, house prices could continue to surprise on the upside." There is always the possibility that places like Cornwall and towns along the south coast are in a bubble and prices are about to burst, said Pryor, "but the banks and local agents seem convinced that the momentum will keep prices on the up for a long time yet. Mortgage lender Nationwide said its measure of annual house price increases chalked up its second-biggest monthly rise in 15 years in August, putting to bed fears that the end of the government's stamp duty tax break, which prompted a fall in the number of homes changing hands during July, would bring the market to a juddering halt Prices were up 11% on a year ago, said Nationwide, and remain about 13% above pre-pandemic levels, according to official data. Adding to the feverish activity, which has seen some English agents adopt the well-wom Scottish system of sealed bids amid claims of gazumping, new home builders have battled steel and timber shortages and an exodus of staff following Brexit to construct new homes. Many have seen their profits soar Wishart said the end of the furlough scheme on 30 September, which is expected to push unemployment higher, posed only a small risk to rising prices In May 2020, it was a very different story. The first lockdown meant buyers could no longer view properties except online, sellers took their homes off the market and sales collapsed. Two months later Rishi Sunak responded to calls for government support by extending the help-to-buy scheme for first time buyers and cutting stamp duty on homes worth less than £500,000. Figures for August 2020 revealed a spectacular turnaround. Mortgage approvals jumped from 66.300 in July to 84.700, according to Bank of England figures, their highest level since October 2007. Recent analysis of the government's actions by the Resolution Foundation thinktank argued that the £4bn stamp duty subsidy was wasted on sparking a market to life that had already begun to recover and was always going to enjoy stellar growth It said ultra low interest rates, the demand for more spacious properties during the pandemic and the pent up savings of those kept in work by the furlough scheme was enough to spur buying activity without extra incentives from the Treasury Source: Inman (2021)
