15 PURLEY KNOLL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Croydon local authority area over time, sourced from the HPI. The two 15 PURLEY KNOLL sales from July 1995 and October 2003 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 July 1995 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the October 2003 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 15 PURLEY KNOLL be worth now?

This is based on house price inflation of 113.5%, between October 2003 and February 2025, for detached houses, in the Croydon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 113.5% inflationary increase is applied to the most recent sale price for 15 PURLEY KNOLL of £420,000 on 31st October 2003. For the value to have increased from £420,000 to £896,837 over the 22 years and eight months to February 2025, the following assumptions must hold true:
