5 THORNTON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Fareham local authority area over time, sourced from the HPI. The two 5 THORNTON AVENUE sales from August 2015 and March 2021 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 August 2015 sale was for 96% above the HPI. So the extrapolation line tracks at 96% above the HPI over time, until the March 2021 sale, where it rises to 149% above the HPI. The line then continues to track at 149% above the HPI.

What might 5 THORNTON AVENUE be worth now?

5 THORNTON AVENUE might now be worth an estimated £1,362,957.

This is based on house price inflation of 13.6%, between March 2021 and December 2024, for detached houses, in the Fareham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 13.6% inflationary increase is applied to the most recent sale price for 5 THORNTON AVENUE of £1,200,000 on 4th March 2021. For the value to have increased from £1,200,000 to £1,362,957 over the two years and three months to December 2024, the following assumptions must hold true:

• The value of 5 THORNTON AVENUE has moved in line with the HPI for detached houses in the Fareham local authority area.
• The March 2021 sale price of £1,200,000 represented a fair market value for the property.
