41% of homeowners in London would try to sell their property for a higher price than their estate agent quoted.
New research from online estate agency eMoov has warned that people could see their homes failing to sell for months because they have listed their properties way over their real value.
Its survey also found 31% of Londoners say getting the highest price is the most important factor when selling a home.
While only 3% would list their property at a lower price than they've been quoted by the estate agent.
Across the UK, it found the average home sold for £180,252 according to the latest Land registry report yet the average asking price on property website Rightmove is £279,000.
Asking prices for property in London have seen the largest monthly drop across England and Wales. According to website Rightmove, the average figure in the capital is just over 550 thousand pounds - that's almost 6 percent lower than in July. There has, though, been a 20 per cent year-on-year jump in the number of newly-marketed homes.
Properties in London are selling ten days faster than they did this time last year.
A report by Post Office Mortgages reveals the average property in the capital sells four weeks faster than the rest of the UK and is on the market for an average of 32 days.
