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 18 MOUNTAIN RISE sales from September 2009 and October 2017 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 September 2009 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the October 2017 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.
18 MOUNTAIN RISE might now be worth an estimated £225,518.
This is based on house price inflation of 55.5%, between October 2017 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 55.5% inflationary increase is applied to the most recent sale price for 18 MOUNTAIN RISE of £145,000 on 11th October 2017. For the value to have increased from £145,000 to £225,518 over the six years and ten months to December 2024, the following assumptions must hold true:
