26 BLENHEIM CLOSE 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 26 BLENHEIM CLOSE sales from May 2019 and March 2025 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 2019 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the March 2025 sale, where it rises to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 26 BLENHEIM CLOSE be worth now?

This is based on house price deflation of 2.6%, between March 2025 and June 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 2.6% deflationary decrease is applied to the most recent sale price for 26 BLENHEIM CLOSE of £422,000 on 4th March 2025. For the value to have decreased from £422,000 to £411,160 over the nine months to June 2025, the following assumptions must hold true:
