Land registry data shows two sales for 21 NORTHPARK since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Stockton-on-Tees local authority area for the corresponding sale date. Both of the two 21 NORTHPARK sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2003 13 JUN | £84,000 | £70,360 | 19% above HPI |
1996 13 SEP | £51,500 | £41,994 | 23% above HPI |
The below graph shows the average semi-detached house price in the Stockton-on-Tees local authority area over time, sourced from the HPI. The two 21 NORTHPARK sales from September 1996 and June 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 September 1996 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the June 2003 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.

21 NORTHPARK might now be worth an estimated £194,621.
This is based on house price inflation of 131.7%, between June 2003 and May 2026, for semi-detached houses, in the Stockton-on-Tees local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 131.7% inflationary increase is applied to the most recent sale price for 21 NORTHPARK of £84,000 on 13th June 2003. For the value to have increased from £84,000 to £194,621 over the 23 years and one month to May 2026, the following assumptions must hold true:
