12A GREEN LANE 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 two 12A GREEN LANE sales from October 2007 and December 2019 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 October 2007 sale was for 88% above the HPI. So the extrapolation line tracks at 88% above the HPI over time, until the December 2019 sale, where it falls to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 12A GREEN LANE be worth now?

12A GREEN LANE might now be worth an estimated £1,420,458.

This is based on house price inflation of 11.2%, between December 2019 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 11.2% inflationary increase is applied to the most recent sale price for 12A GREEN LANE of £1,277,000 on 2nd December 2019. For the value to have increased from £1,277,000 to £1,420,458 over the five years to December 2024, the following assumptions must hold true:

• The value of 12A GREEN LANE has moved in line with the HPI for detached houses in the Watford local authority area.
• The December 2019 sale price of £1,277,000 represented a fair market value for the property.
• The size, condition, and specification of 12A GREEN LANE has not materially changed since December 2019.
