The ongoing boom means that Southend remains in the top 10 areas for house price growth across the whole of the UK, according to analysis by Hometrack.
The average price across Southend in June 2015 was £173,699, with a detached property costing £361,688, a semi-detached costing £226,535, a terraced house costing £169,446 and flats going for an average of £120,388.
Property experts say the upward trend will continue as home buyers are priced out of London.
Richard Donnell, Research and Insight Director at Hometrack, said growth was “coming out of the cheapest parts of London and in the commuter areas”.
He said that lack of affordability in London was causing homebuyers to look at markets just outside the M25 area, where employment and earnings are growing and “there’s value for money in housing”.
He added that affordable and accessible markets like Southend will continue to increase.
Luton saw the greatest house price growth (13.1%), followed by Oxford (12.3%) and Milton Keynes (11.4%).
Prices across the whole of London rose by 10.1%, but prices in prime central London only increased by 1.6%, placing it in the bottom three of the house price index.
Changes to taxation, including stamp duty changes affecting the most expensive properties, are blamed for the slowdown in prime areas.
