| Date | Price | HPI Price | Variation from HPI |

The below graph shows the average semi-detached house price in the Croydon local authority area over time, sourced from the HPI. The two 25 HARTLEY DOWN sales from November 2002 and January 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 November 2002 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the January 2003 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.

25 HARTLEY DOWN might now be worth an estimated £569,493.
This is based on house price inflation of 140.3%, between January 2003 and May 2026, for semi-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 140.3% inflationary increase is applied to the most recent sale price for 25 HARTLEY DOWN of £237,000 on 21st January 2003. For the value to have increased from £237,000 to £569,493 over the 22 years and eight months to May 2026, the following assumptions must hold true:
