9 MOUNTAIN RISE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Merthyr Tydfil local authority area over time, sourced from the HPI. The two 9 MOUNTAIN RISE sales from May 2007 and November 2013 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 May 2007 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the November 2013 sale, where it falls to 48% above the HPI. The line then continues to track at 48% above the HPI.

What might 9 MOUNTAIN RISE be worth now?

9 MOUNTAIN RISE might now be worth an estimated £187,854.

This is based on house price inflation of 84.2%, between November 2013 and May 2026, for terraced 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 84.2% inflationary increase is applied to the most recent sale price for 9 MOUNTAIN RISE of £102,000 on 1st November 2013. For the value to have increased from £102,000 to £187,854 over the thirteen years and six months to May 2026, the following assumptions must hold true:

• The value of 9 MOUNTAIN RISE has moved in line with the HPI for terraced houses in the Merthyr Tydfil local authority area.
• The November 2013 sale price of £102,000 represented a fair market value for the property.
• The size, condition, and specification of 9 MOUNTAIN RISE has not materially changed since November 2013.
