20 LON CAE PORTH Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The four 20 LON CAE PORTH sales between May 2004 and January 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 September 2015 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the January 2024 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 20 LON CAE PORTH be worth now?
