21 GADE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Watford local authority area over time, sourced from the HPI. The two 21 GADE AVENUE sales from April 2003 and June 2015 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 April 2003 sale was for 51% above the HPI. So the extrapolation line tracks at 51% above the HPI over time, until the June 2015 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

What might 21 GADE AVENUE be worth now?

21 GADE AVENUE might now be worth an estimated £807,049.

This is based on house price inflation of 38%, between June 2015 and December 2024, for semi-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 38% inflationary increase is applied to the most recent sale price for 21 GADE AVENUE of £585,000 on 19th June 2015. For the value to have increased from £585,000 to £807,049 over the eight years and six months to December 2024, the following assumptions must hold true:

• The value of 21 GADE AVENUE has moved in line with the HPI for semi-detached houses in the Watford local authority area.
• The June 2015 sale price of £585,000 represented a fair market value for the property.
