25 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 25 THORNTON AVENUE sales from August 2002 and November 2018 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 2002 sale was for 240% above the HPI. So the extrapolation line tracks at 240% above the HPI over time, until the November 2018 sale, where it falls to 116% above the HPI. The line then continues to track at 116% above the HPI.

What might 25 THORNTON AVENUE be worth now?

This is based on house price inflation of 18.3%, between November 2018 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 18.3% inflationary increase is applied to the most recent sale price for 25 THORNTON AVENUE of £1,000,001 on 1st November 2018. For the value to have increased from £1,000,001 to £1,183,404 over the five years and eleven months to December 2024, the following assumptions must hold true:
