AMBERLEY 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 AMBERLEY sales from March 2006 and January 2009 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 2006 sale was for 202% above the HPI. So the extrapolation line tracks at 202% above the HPI over time, until the January 2009 sale, where it rises to 241% above the HPI. The line then continues to track at 241% above the HPI.

What might AMBERLEY be worth now?

AMBERLEY might now be worth an estimated £5,366,691.

This is based on house price inflation of 104.4%, between January 2009 and July 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 104.4% inflationary increase is applied to the most recent sale price for AMBERLEY of £2,625,000 on 6th January 2009. For the value to have increased from £2,625,000 to £5,366,691 over the fifteen years and six months to July 2025, the following assumptions must hold true:

• The value of AMBERLEY has moved in line with the HPI for detached houses in the Barnet local authority area.
• The January 2009 sale price of £2,625,000 represented a fair market value for the property.
• The size, condition, and specification of AMBERLEY has not materially changed since January 2009.
