Six of the 10 slowest-selling postcodes can be found within the M25 and the capital is responsible for all three areas found to be the hardest to sell a property in.
At an average of 16 viewings per sale, house sellers in London have a much tougher job than their equivalents in the North of England, where homes go after just 11 viewings.
Sellers in Carlisle can lay claim to having life the easiest, though, with houses here being viewed just six times before being sold.
Whilst vendors in Glasgow, Wrexham and Perth, which all average seven viewings, are not far behind.
Mark Readings, House Network CEO, said: “What’s clear from our research is just how relatively simple it is to sell your house, even in London where vendors have to work that bit harder to take those ‘For Sale’ signs down.
“When you place this into the context that selling a house is almost certainly the biggest sale we make in our lives, 15 viewings is no time at all.
“The North/South divide in the property market is well documented, but it’s interesting to see that it also rings true with how many viewings per sale and not just price.”
The report pulled together the average viewing numbers across the country using data from over 8,500 house sales.
