21 MAPESBURY ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Brent local authority area over time, sourced from the HPI. The two 21 MAPESBURY ROAD sales from December 1996 and June 2004 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 December 1996 sale was for 110% above the HPI. So the extrapolation line tracks at 110% above the HPI over time, until the June 2004 sale, where it rises to 165% above the HPI. The line then continues to track at 165% above the HPI.

What might 21 MAPESBURY ROAD be worth now?

This is based on house price inflation of 141.9%, between June 2004 and February 2025, for detached houses, in the Brent local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 141.9% inflationary increase is applied to the most recent sale price for 21 MAPESBURY ROAD of £1,400,000 on 17th June 2004. For the value to have increased from £1,400,000 to £3,386,941 over the 21 years and four months to February 2025, the following assumptions must hold true:

• The value of 21 MAPESBURY ROAD has moved in line with the HPI for detached houses in the Brent local authority area.
• The June 2004 sale price of £1,400,000 represented a fair market value for the property.
