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

| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2003 5 SEP | £120,000 | £90,322 | 33% above HPI |
1996 25 OCT | £60,000 | £43,110 | 39% above HPI |

The below graph shows the average semi-detached house price in the Sheffield local authority area over time, sourced from the HPI. The three 12 TOP SIDE sales between July 1996 and September 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 October 1996 sale was for 39% above the HPI. So the extrapolation line tracks at 39% above the HPI over time, until the September 2003 sale, where it falls to 33% above the HPI. The line then continues to track at 33% above the HPI.

12 TOP SIDE might now be worth an estimated £310,687.
This is based on house price inflation of 158.9%, between September 2003 and August 2025, for semi-detached houses, in the Sheffield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 158.9% inflationary increase is applied to the most recent sale price for 12 TOP SIDE of £120,000 on 5th September 2003. For the value to have increased from £120,000 to £310,687 over the 22 years and one month to August 2025, the following assumptions must hold true:
