3 LON PENLLYN 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 two 3 LON PENLLYN sales from August 1997 and October 2000 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 August 1997 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the October 2000 sale, where it rises to 13% below the HPI. The line then continues to track at 13% below the HPI.

What might 3 LON PENLLYN be worth now?
