A survey of more than 2,000 homeowners found that they estimated the value of their homes on average at £190,175 – an overestimation of at least £35,000 on the real average value. The difference between perceived prices and what is actually paid, based on figures from the Land Registry, are widest in the East and South East of the UK – with an average difference between asking price and actual sale price of around £50,000.
