12 CONWAY GROVE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Merthyr Tydfil local authority area over time, sourced from the HPI. The two 12 CONWAY GROVE sales from January 2003 and May 2010 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 2003 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the May 2010 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.

What might 12 CONWAY GROVE be worth now?

12 CONWAY GROVE might now be worth an estimated £182,093.

This is based on house price inflation of 70.2%, between May 2010 and June 2025, for semi-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 70.2% inflationary increase is applied to the most recent sale price for 12 CONWAY GROVE of £107,000 on 28th May 2010. For the value to have increased from £107,000 to £182,093 over the fourteen years and eleven months to June 2025, the following assumptions must hold true:

• The value of 12 CONWAY GROVE has moved in line with the HPI for semi-detached houses in the Merthyr Tydfil local authority area.
• The May 2010 sale price of £107,000 represented a fair market value for the property.
