21 BYRON AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Winchester local authority area over time, sourced from the HPI. The two 21 BYRON AVENUE sales from May 1995 and September 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 May 1995 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the September 2021 sale, where it rises to 43% above the HPI. The line then continues to track at 43% above the HPI.

What might 21 BYRON AVENUE be worth now?

This is based on house price inflation of 11%, between September 2021 and February 2025, for semi-detached houses, in the Winchester local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 11% inflationary increase is applied to the most recent sale price for 21 BYRON AVENUE of £631,000 on 29th September 2021. For the value to have increased from £631,000 to £700,139 over the four years and seven months to February 2025, the following assumptions must hold true:
