The below graph shows the average detached house price in the Sunderland local authority area over time, sourced from the HPI. The two 12 DALMAHOY sales from July 1998 and August 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 1998 sale was for 61% above the HPI. So the extrapolation line tracks at 61% above the HPI over time, until the August 2020 sale, where it rises to 88% above the HPI. The line then continues to track at 88% above the HPI.
12 DALMAHOY might now be worth an estimated £491,376.
This is based on house price inflation of 30.2%, between August 2020 and February 2025, for detached houses, in the Sunderland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 30.2% inflationary increase is applied to the most recent sale price for 12 DALMAHOY of £377,500 on 17th August 2020. For the value to have increased from £377,500 to £491,376 over the five years and six months to February 2025, the following assumptions must hold true:
