|---|---|---|---|

The below graph shows the average semi-detached house price in the Crawley local authority area over time, sourced from the HPI. The four 17 ALPHA ROAD sales between September 1996 and January 2011 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 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the January 2011 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.

17 ALPHA ROAD might now be worth an estimated £347,563.
This is based on house price inflation of 106.9%, between January 2011 and April 2026, for semi-detached houses, in the Crawley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 106.9% inflationary increase is applied to the most recent sale price for 17 ALPHA ROAD of £168,000 on 13th January 2011. For the value to have increased from £168,000 to £347,563 over the fourteen years and nine months to April 2026, the following assumptions must hold true:
