Andy Hulme, mortgages director at Lloyds Bank, said: "Market towns are important hubs of social interaction and cohesion, as well as providers of employment and support for local business.
“Market towns are also, in most cases, very attractive places to live. This is reflected in the majority of market towns having higher property prices than their surrounding counties – a premium that increased in the past decade.
"Homebuyers continue to be attracted to the high quality of life, architecture, history, setting and community spirit offered by market towns and are prepared to pay a premium to live there."
The most affordable market town is Ferryhill in County Durham, with house prices averaging £85,763.
Premiums for market towns compared to their county stand at £24,766 on average, as market towns have seen prices rise by £505 per month over the course of the decade.
