20 MARDALE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Worthing local authority area over time, sourced from the HPI. The two 20 MARDALE ROAD sales from March 2004 and August 2015 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 March 2004 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the August 2015 sale, where it falls to 38% below the HPI. The line then continues to track at 38% below the HPI.

What might 20 MARDALE ROAD be worth now?

This is based on house price inflation of 38.5%, between August 2015 and December 2024, for detached houses, in the Worthing local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 38.5% inflationary increase is applied to the most recent sale price for 20 MARDALE ROAD of £273,000 on 14th August 2015. For the value to have increased from £273,000 to £378,219 over the eight years and eight months to December 2024, the following assumptions must hold true:
