31 HEOLGERRIG Price Paid vs. HPI Average

The below graph shows the average detached house price in the Merthyr Tydfil local authority area over time, sourced from the HPI. The three 31 HEOLGERRIG sales between April 2017 and December 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 June 2023 sale was for 58% below the HPI. So the extrapolation line tracks at 58% below the HPI over time, until the December 2024 sale, where it rises to 38% below the HPI. The line then continues to track at 38% below the HPI.

What might 31 HEOLGERRIG be worth now?

The 5.4% deflationary decrease is applied to the most recent sale price for 31 HEOLGERRIG of £157,000 on 12th December 2024. For the value to have decreased from £157,000 to £148,551 over the one year and ten months to February 2025, the following assumptions must hold true:
