Karen Noye, mortgage expert at Quilter, said: “April’s house price index shows that some froth is finally coming out of the housing market with a 1.9 per cent drop in just a month since March 2021. This may be the first signal of what is to come as it is likely buyers no longer feel they can complete on a property before the June stamp duty holiday tapering begins.”
Sarah Coles, personal finance analyst at Hargreaves Lansdown, said: “House prices dropped in April, which is bound to unsettle homeowners after almost a year of accelerating price rises. At this stage, we are not expecting this to be the ultimate turning point for the market, but it’s a useful wake-up call for buyers, and a reminder that house prices aren’t a one-way street.”
