125 TAI GILFACH 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 125 TAI GILFACH sales from July 2000 and October 2015 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 July 2000 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the October 2015 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.

What might 125 TAI GILFACH be worth now?

125 TAI GILFACH might now be worth an estimated £183,306.

This is based on house price inflation of 66.6%, between October 2015 and December 2024, 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 66.6% inflationary increase is applied to the most recent sale price for 125 TAI GILFACH of £110,000 on 22nd October 2015. For the value to have increased from £110,000 to £183,306 over the eight years and ten months to December 2024, the following assumptions must hold true:

• The value of 125 TAI GILFACH has moved in line with the HPI for semi-detached houses in the Merthyr Tydfil local authority area.
• The October 2015 sale price of £110,000 represented a fair market value for the property.
