The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The three 25 LON GWYNFRYN sales between October 1998 and August 2022 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 October 2021 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the August 2022 sale, where it rises to 65% above the HPI. The line then continues to track at 65% above the HPI.
25 LON GWYNFRYN might now be worth an estimated £341,243.
