20 ONSLOW DRIVE 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 five 20 ONSLOW DRIVE sales between July 1995 and July 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 March 2022 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the July 2024 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might 20 ONSLOW DRIVE be worth now?

This is based on house price inflation of 4.3%, between July 2024 and March 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 4.3% inflationary increase is applied to the most recent sale price for 20 ONSLOW DRIVE of £475,000 on 22nd July 2024. For the value to have increased from £475,000 to £495,397 over the one year and four months to March 2025, the following assumptions must hold true:

• The value of 20 ONSLOW DRIVE has moved in line with the HPI for semi-detached houses in the South Oxfordshire local authority area.
