11 THE MOUNT 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 two 11 THE MOUNT sales from September 1997 and August 2007 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 1997 sale was for 87% above the HPI. So the extrapolation line tracks at 87% above the HPI over time, until the August 2007 sale, where it falls to 45% above the HPI. The line then continues to track at 45% above the HPI.

What might 11 THE MOUNT be worth now?

11 THE MOUNT might now be worth an estimated £674,157.

This is based on house price inflation of 74.2%, between August 2007 and February 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 74.2% inflationary increase is applied to the most recent sale price for 11 THE MOUNT of £387,000 on 17th August 2007. For the value to have increased from £387,000 to £674,157 over the eighteen years and six months to February 2025, the following assumptions must hold true:

• The value of 11 THE MOUNT has moved in line with the HPI for semi-detached houses in the South Oxfordshire local authority area.
• The August 2007 sale price of £387,000 represented a fair market value for the property.
• The size, condition, and specification of 11 THE MOUNT has not materially changed since August 2007.
