23 BISHOPS AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The two 23 BISHOPS AVENUE sales from May 2017 and November 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 May 2017 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the November 2019 sale, where it rises to 51% above the HPI. The line then continues to track at 51% above the HPI.

What might 23 BISHOPS AVENUE be worth now?

23 BISHOPS AVENUE might now be worth an estimated £1,760,406.

This is based on house price inflation of 11.8%, between November 2019 and August 2025, for detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 11.8% inflationary increase is applied to the most recent sale price for 23 BISHOPS AVENUE of £1,575,000 on 22nd November 2019. For the value to have increased from £1,575,000 to £1,760,406 over the six years and three months to August 2025, the following assumptions must hold true:

• The value of 23 BISHOPS AVENUE has moved in line with the HPI for detached houses in the Three Rivers local authority area.
• The November 2019 sale price of £1,575,000 represented a fair market value for the property.
