Eight out of ten homeowners uncertain about their home’s true value with two-thirds missing out on potential gains by wildly under-valuing their property

The data, which compared seller expectations with actual estate agent valuations, found that two-thirds of homeowners tend to undervalue their homes, missing out on potential gains. A third of homeowners who undervalued their property did so by £100,000 or more, leading to an unexpected windfall when they did sell.
