JARVIS COTTAGE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The four JARVIS COTTAGE sales between May 1999 and October 2024 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 2012 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the October 2024 sale, where it rises to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might JARVIS COTTAGE be worth now?
