The below graph shows the average semi-detached house price in the Barnet local authority area over time, sourced from the HPI. The two 18 THE GROVE sales from January 2008 and May 2014 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 January 2008 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the May 2014 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

18 THE GROVE might now be worth an estimated £715,999.
This is based on house price inflation of 43.2%, between May 2014 and May 2026, for semi-detached houses, in the Barnet local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 43.2% inflationary increase is applied to the most recent sale price for 18 THE GROVE of £499,950 on 7th May 2014. For the value to have increased from £499,950 to £715,999 over the twelve years to May 2026, the following assumptions must hold true:
