20 THEOBALDS ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southend-on-Sea local authority area over time, sourced from the HPI. The two 20 THEOBALDS ROAD sales from May 2004 and January 2010 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the May 2004 sale was for 90% above the HPI. So the extrapolation line tracks at 90% above the HPI over time, until the January 2010 sale, where it rises to 133% above the HPI. The line then continues to track at 133% above the HPI.

What might 20 THEOBALDS ROAD be worth now?

20 THEOBALDS ROAD might now be worth an estimated £952,956.

This is based on house price inflation of 100.6%, between January 2010 and June 2025, for semi-detached houses, in the Southend-on-Sea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 100.6% inflationary increase is applied to the most recent sale price for 20 THEOBALDS ROAD of £475,000 on 28th January 2010. For the value to have increased from £475,000 to £952,956 over the fourteen years and seven months to June 2025, the following assumptions must hold true:

• The value of 20 THEOBALDS ROAD has moved in line with the HPI for semi-detached houses in the Southend-on-Sea local authority area.
• The January 2010 sale price of £475,000 represented a fair market value for the property.
