Judged by the site's January traffic which saw a 16 per cent increase in users, Brighton's visitor average is almost four times that for the rest of the country.
Manchester is the second most active place according to propertyfinder.com data, whilst Watford comes in third.
Unsurprisingly, London came top on overall activity however when adjusted for the number of households, the capital fared no better than the rest of the country.
Propertyfinder.com also reported an increase in lead delivery to estate agents from buyers looking for property and from sellers seeking an agent to value their home. The number of such email enquiries is up 60 per cent on the same period in 2007.
