17 CASTLE CLOSE 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 three 17 CASTLE CLOSE sales between February 1996 and July 2014 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 August 2003 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the July 2014 sale, where it falls to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 17 CASTLE CLOSE be worth now?

17 CASTLE CLOSE might now be worth an estimated £518,319.

This is based on house price inflation of 51.3%, between July 2014 and February 2025, for 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).
