25 SYDENHAM CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cherwell local authority area over time, sourced from the HPI. The two 25 SYDENHAM CLOSE sales from July 2005 and May 2016 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 July 2005 sale was for 63% above the HPI. So the extrapolation line tracks at 63% above the HPI over time, until the May 2016 sale, where it falls to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might 25 SYDENHAM CLOSE be worth now?

This is based on house price inflation of 22.2%, between May 2016 and February 2025, for detached houses, in the Cherwell local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 22.2% inflationary increase is applied to the most recent sale price for 25 SYDENHAM CLOSE of £510,000 on 25th May 2016. For the value to have increased from £510,000 to £623,176 over the nine years and three months to February 2025, the following assumptions must hold true:
