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 28 WILLOWTREE AVENUE sales between April 1999 and August 2006 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 March 2003 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the August 2006 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

28 WILLOWTREE AVENUE might now be worth an estimated £196,253.
This is based on house price inflation of 26.7%, between August 2006 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 26.7% inflationary increase is applied to the most recent sale price for 28 WILLOWTREE AVENUE of £154,950 on 18th August 2006. For the value to have increased from £154,950 to £196,253 over the twenty years and four months to April 2026, the following assumptions must hold true:
