24 OBSERVATORY CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the South Oxfordshire local authority area over time, sourced from the HPI. The three 24 OBSERVATORY CLOSE sales between December 2002 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 October 2020 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the March 2025 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might 24 OBSERVATORY CLOSE be worth now?
