21 GROSVENOR GARDENS 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 three 21 GROSVENOR GARDENS sales between October 1997 and August 2016 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 1998 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the August 2016 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 21 GROSVENOR GARDENS be worth now?

This is based on house price inflation of 12.6%, between August 2016 and February 2025, 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 12.6% inflationary increase is applied to the most recent sale price for 21 GROSVENOR GARDENS of £1,550,000 on 4th August 2016. For the value to have increased from £1,550,000 to £1,744,885 over the nine years and six months to February 2025, the following assumptions must hold true:

• The value of 21 GROSVENOR GARDENS has moved in line with the HPI for detached houses in the Barnet local authority area.
• The August 2016 sale price of £1,550,000 represented a fair market value for the property.
