11 BLACKTHORN GRANGE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The two 11 BLACKTHORN GRANGE sales from May 2018 and June 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 2018 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the June 2025 sale, where it rises to 28% below the HPI. The line then continues to track at 28% below the HPI.

What might 11 BLACKTHORN GRANGE be worth now?
