The below graph shows the average semi-detached house price in the County Durham local authority area over time, sourced from the HPI. The two 49 MARINERS WAY sales from November 2012 and June 2021 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 November 2012 sale was for 61% above the HPI. So the extrapolation line tracks at 61% above the HPI over time, until the June 2021 sale, where it falls to 55% above the HPI. The line then continues to track at 55% above the HPI.

49 MARINERS WAY might now be worth an estimated £217,098.
This is based on house price inflation of 20.6%, between June 2021 and April 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 20.6% inflationary increase is applied to the most recent sale price for 49 MARINERS WAY of £179,995 on 7th June 2021. For the value to have increased from £179,995 to £217,098 over the five years and two months to April 2026, the following assumptions must hold true:
