11 DOWNSIDE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The three 11 DOWNSIDE sales between May 2009 and November 2024 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 October 2014 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the November 2024 sale, where it falls to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 11 DOWNSIDE be worth now?

11 DOWNSIDE might now be worth an estimated £435,611.

This is based on house price deflation of 1%, between November 2024 and July 2025, for semi-detached houses, in the South Oxfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1% deflationary decrease is applied to the most recent sale price for 11 DOWNSIDE of £440,000 on 11th November 2024. For the value to have decreased from £440,000 to £435,611 over the one year and four months to July 2025, the following assumptions must hold true:

• The value of 11 DOWNSIDE has moved in line with the HPI for semi-detached houses in the South Oxfordshire local authority area.
• The November 2024 sale price of £440,000 represented a fair market value for the property.
• The size, condition, and specification of 11 DOWNSIDE has not materially changed since November 2024.
