The below table shows the price paid for the three sales, along with the average semi-detached price in the Barnsley local authority area for the corresponding sale date.

| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2014 9 MAY | £100,000 | £99,603 | Close to HPI |

The below graph shows the average semi-detached house price in the Barnsley local authority area over time, sourced from the HPI. The three 121 BLENHEIM ROAD sales between June 2001 and May 2014 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 October 2003 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the May 2014 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.

121 BLENHEIM ROAD might now be worth an estimated £164,789.
This is based on house price inflation of 64.8%, between May 2014 and August 2025, for semi-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 64.8% inflationary increase is applied to the most recent sale price for 121 BLENHEIM ROAD of £100,000 on 9th May 2014. For the value to have increased from £100,000 to £164,789 over the ten years and nine months to August 2025, the following assumptions must hold true:
