17 WESTERDALE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Chelmsford local authority area over time, sourced from the HPI. The three 17 WESTERDALE sales between September 1997 and February 2025 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 September 2012 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the February 2025 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 17 WESTERDALE be worth now?

This is based on house price inflation of 5.5%, between February 2025 and June 2025, for semi-detached houses, in the Chelmsford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 5.5% inflationary increase is applied to the most recent sale price for 17 WESTERDALE of £485,600 on 28th February 2025. For the value to have increased from £485,600 to £512,185 over the eight months to June 2025, the following assumptions must hold true:
