The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The five 15 THE SQUARE sales between January 1997 and October 2024 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 May 2017 sale was for 111% above the HPI. So the extrapolation line tracks at 111% above the HPI over time, until the October 2024 sale, where it falls to 86% above the HPI. The line then continues to track at 86% above the HPI.

15 THE SQUARE might now be worth an estimated £211,281.
This is based on house price inflation of 5.7%, between October 2024 and May 2026, for terraced houses, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.7% inflationary increase is applied to the most recent sale price for 15 THE SQUARE of £199,950 on 4th October 2024. For the value to have increased from £199,950 to £211,281 over the two years and five months to May 2026, the following assumptions must hold true:
