11 ORION AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Gosport local authority area over time, sourced from the HPI. The four 11 ORION AVENUE sales between October 2002 and September 2010 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 September 2006 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the September 2010 sale, where it rises to 54% above the HPI. The line then continues to track at 54% above the HPI.

What might 11 ORION AVENUE be worth now?

This is based on house price inflation of 76.9%, between September 2010 and October 2025, for semi-detached houses, in the Gosport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 76.9% inflationary increase is applied to the most recent sale price for 11 ORION AVENUE of £265,000 on 22nd September 2010. For the value to have increased from £265,000 to £468,850 over the fourteen years and eleven months to October 2025, the following assumptions must hold true:
