18 PORTMAN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bournemouth Christchurch and Poole local authority area over time, sourced from the HPI. The three 18 PORTMAN ROAD sales between July 1996 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 April 2010 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the October 2024 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 18 PORTMAN ROAD be worth now?
