40 THE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Watford local authority area over time, sourced from the HPI. The three 40 THE AVENUE sales between July 2001 and May 2020 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 2010 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the May 2020 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might 40 THE AVENUE be worth now?

40 THE AVENUE might now be worth an estimated £898,478.

This is based on house price inflation of 7%, between May 2020 and December 2024, for detached houses, in the Watford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 7% inflationary increase is applied to the most recent sale price for 40 THE AVENUE of £840,000 on 26th May 2020. For the value to have increased from £840,000 to £898,478 over the three years and five months to December 2024, the following assumptions must hold true:

• The value of 40 THE AVENUE has moved in line with the HPI for detached houses in the Watford local authority area.
• The May 2020 sale price of £840,000 represented a fair market value for the property.
• The size, condition, and specification of 40 THE AVENUE has not materially changed since May 2020.
