The below table shows the price paid for the two sales, along with the average detached price in the Northumberland local authority area for the corresponding sale date. Both of the two 20 BLACKDENE sales were for below 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 |
|---|---|---|---|

The below graph shows the average detached house price in the Northumberland local authority area over time, sourced from the HPI. The two 20 BLACKDENE sales from July 2017 and March 2020 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 July 2017 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the March 2020 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.

20 BLACKDENE might now be worth an estimated £315,112.
This is based on house price inflation of 37%, between March 2020 and May 2026, for detached houses, in the Northumberland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 37% inflationary increase is applied to the most recent sale price for 20 BLACKDENE of £230,000 on 19th March 2020. For the value to have increased from £230,000 to £315,112 over the five years and ten months to May 2026, the following assumptions must hold true:
