The difference between the two properties is £2.49m.
Almost one in five Brits, 19%, incorrectly guessed that a four-bedroom barn conversion in Blackburn cost more than a two-bedroom penthouse in London, according to HouseSimple.
The difference between the two properties is £2.49m, data collected by HouseSimple shows.
Furthermore, 35% of those living in Britain inaccurately estimated the cost of a five-bedroom detached house in Norwich, and a six-bedroom detached house in Sudbury, Suffolk.
Of individuals living in Leeds, 62%, correctly predicted that a five-bedroom semi-detached property in the city is worth more than a three-bedroom detached house in Nottingham.
However, 62% of those in Nottingham incorrectly assumed that the house in their city was the priciest.
Sam Mitchell, chief executive at Housesimple, said: “Property prices are a national obsession, so it’s interesting to see from the results that the majority of Brits may not know what they could get for their money in other parts of the country.
“That’s why we’ve put together a quiz for people to test themselves when it comes to their knowledge on property costs across the UK, people could be surprised that they can get more for their money elsewhere.”
