21 NORTHWICK AVENUE 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 NORTHWICK AVENUE sales from July 1999 and November 1999 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 July 1999 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the November 1999 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 21 NORTHWICK AVENUE be worth now?

21 NORTHWICK AVENUE might now be worth an estimated £1,090,636.

This is based on house price inflation of 319.5%, between November 1999 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 319.5% inflationary increase is applied to the most recent sale price for 21 NORTHWICK AVENUE of £260,000 on 18th November 1999. For the value to have increased from £260,000 to £1,090,636 over the 26 years and nine months to February 2025, the following assumptions must hold true:

• The value of 21 NORTHWICK AVENUE has moved in line with the HPI for detached houses in the Brent local authority area.
• The November 1999 sale price of £260,000 represented a fair market value for the property.
