21 HIGHWOOD GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 21 HIGHWOOD GROVE sales from November 2003 and December 2011 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 2003 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the December 2011 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 21 HIGHWOOD GROVE be worth now?

21 HIGHWOOD GROVE might now be worth an estimated £1,560,693.

This is based on house price inflation of 67.8%, between December 2011 and December 2024, for 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 67.8% inflationary increase is applied to the most recent sale price for 21 HIGHWOOD GROVE of £930,000 on 22nd December 2011. For the value to have increased from £930,000 to £1,560,693 over the thirteen years to December 2024, the following assumptions must hold true:

• The value of 21 HIGHWOOD GROVE has moved in line with the HPI for detached houses in the Barnet local authority area.
• The December 2011 sale price of £930,000 represented a fair market value for the property.
• The size, condition, and specification of 21 HIGHWOOD GROVE has not materially changed since December 2011.
