12 GOLWG Y MYNYDD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The three 12 GOLWG Y MYNYDD sales between February 1999 and February 2020 have been plotted on the graph.

For example, the May 2011 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the February 2020 sale, where it falls to 28% below the HPI. The line then continues to track at 28% below the HPI.

What might 12 GOLWG Y MYNYDD be worth now?
