11 FARNHAM AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The four 11 FARNHAM AVENUE sales between August 2009 and February 2023 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 November 2014 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the February 2023 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.

What might 11 FARNHAM AVENUE be worth now?
