158 SINCLAIR AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cherwell local authority area over time, sourced from the HPI. The two 158 SINCLAIR AVENUE sales from January 2019 and May 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 January 2019 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the May 2025 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 158 SINCLAIR AVENUE be worth now?
