16 PENCAERFENNI LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The four 16 PENCAERFENNI LANE sales between November 2000 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 August 2019 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the September 2025 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.
