29 AWEL Y GRUG Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Gwynedd local authority area over time, sourced from the HPI. The three 29 AWEL Y GRUG sales between April 2009 and February 2024 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 January 2022 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the February 2024 sale, where it falls to 24% above the HPI. The line then continues to track at 24% above the HPI.

What might 29 AWEL Y GRUG be worth now?
