1 CONWAY GROVE 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 two 1 CONWAY GROVE sales from November 1997 and January 2018 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 November 1997 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the January 2018 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 1 CONWAY GROVE be worth now?

1 CONWAY GROVE might now be worth an estimated £246,691.

This is based on house price inflation of 48.6%, between January 2018 and February 2025, for detached houses, in the Merthyr Tydfil local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 48.6% inflationary increase is applied to the most recent sale price for 1 CONWAY GROVE of £166,000 on 5th January 2018. For the value to have increased from £166,000 to £246,691 over the six years and eleven months to February 2025, the following assumptions must hold true:

• The value of 1 CONWAY GROVE has moved in line with the HPI for detached houses in the Merthyr Tydfil local authority area.
• The January 2018 sale price of £166,000 represented a fair market value for the property.
