20 PENTWYN TERRACE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Newport local authority area over time, sourced from the HPI. The two 20 PENTWYN TERRACE sales from June 1996 and April 2025 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 June 1996 sale was for 67% above the HPI. So the extrapolation line tracks at 67% above the HPI over time, until the April 2025 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might 20 PENTWYN TERRACE be worth now?
