The below graph shows the average semi-detached house price in the Reading local authority area over time, sourced from the HPI. The two 51 THIRLMERE AVENUE sales from June 1999 and November 2005 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 June 1999 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the November 2005 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.
51 THIRLMERE AVENUE might now be worth an estimated £436,959.
This is based on house price inflation of 103.3%, between November 2005 and July 2025, for semi-detached houses, in the Reading local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 103.3% inflationary increase is applied to the most recent sale price for 51 THIRLMERE AVENUE of £214,950 on 8th November 2005. For the value to have increased from £214,950 to £436,959 over the twenty years and four months to July 2025, the following assumptions must hold true:
