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 six 15 DUNOTTAR AVENUE sales between June 1997 and November 2025 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 August 2016 sale was for 304% above the HPI. So the extrapolation line tracks at 304% above the HPI over time, until the November 2025 sale, where it falls to 294% above the HPI. The line then continues to track at 294% above the HPI.

15 DUNOTTAR AVENUE might now be worth an estimated £642,690.

The 0.4% deflationary decrease is applied to the most recent sale price for 15 DUNOTTAR AVENUE of £645,000 on 20th November 2025. For the value to have decreased from £645,000 to £642,690 over the one year and six months to May 2026, the following assumptions must hold true:
