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

The below graph shows the average semi-detached house price in the Horsham local authority area over time, sourced from the HPI. The two 15 UNDERMILL ROAD sales from January 1998 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 January 1998 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the October 2003 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

15 UNDERMILL ROAD might now be worth an estimated £471,639.
This is based on house price inflation of 109.6%, between October 2003 and April 2026, for semi-detached houses, in the Horsham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 109.6% inflationary increase is applied to the most recent sale price for 15 UNDERMILL ROAD of £225,000 on 16th October 2003. For the value to have increased from £225,000 to £471,639 over the 23 years and six months to April 2026, the following assumptions must hold true:
