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

The below graph shows the average detached house price in the Barnsley local authority area over time, sourced from the HPI. The three 20 HAISE MOUNT sales between May 1996 and March 2006 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 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the March 2006 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.

20 HAISE MOUNT might now be worth an estimated £305,199.
This is based on house price inflation of 63.2%, between March 2006 and April 2026, for detached houses, in the Barnsley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 63.2% inflationary increase is applied to the most recent sale price for 20 HAISE MOUNT of £187,000 on 21st March 2006. For the value to have increased from £187,000 to £305,199 over the nineteen years and eleven months to April 2026, the following assumptions must hold true:
