| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2000 11 AUG | £233,500 | £79,348 | 194% above HPI |

The below graph shows the average semi-detached house price in the York local authority area over time, sourced from the HPI. The two 135 THE MOUNT sales from September 1998 and August 2000 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 September 1998 sale was for 190% above the HPI. So the extrapolation line tracks at 190% above the HPI over time, until the August 2000 sale, where it rises to 194% above the HPI. The line then continues to track at 194% above the HPI.

135 THE MOUNT might now be worth an estimated £974,966.
This is based on house price inflation of 317.5%, between August 2000 and May 2026, for semi-detached houses, in the York local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 317.5% inflationary increase is applied to the most recent sale price for 135 THE MOUNT of £233,500 on 11th August 2000. For the value to have increased from £233,500 to £974,966 over the 26 years and three months to May 2026, the following assumptions must hold true:
