| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average semi-detached house price in the County Durham local authority area over time, sourced from the HPI. The three 15 CRAGSIDE sales between December 2016 and February 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 September 2018 sale was for 76% above the HPI. So the extrapolation line tracks at 76% above the HPI over time, until the February 2025 sale, where it falls to 58% above the HPI. The line then continues to track at 58% above the HPI.

15 CRAGSIDE might now be worth an estimated £218,140.
This is based on house price inflation of 3.8%, between February 2025 and May 2026, for semi-detached 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 3.8% inflationary increase is applied to the most recent sale price for 15 CRAGSIDE of £210,250 on 3rd February 2025. For the value to have increased from £210,250 to £218,140 over the nine months to May 2026, the following assumptions must hold true:
