21 TREGARN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Newport local authority area over time, sourced from the HPI. The three 21 TREGARN CLOSE sales between October 2003 and September 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 July 2010 sale was for 71% above the HPI. So the extrapolation line tracks at 71% above the HPI over time, until the September 2025 sale, where it falls to 32% above the HPI. The line then continues to track at 32% above the HPI.
