14 BLACKBROOK 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 three 14 BLACKBROOK sales between July 1998 and April 2007 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 March 2002 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the April 2007 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 14 BLACKBROOK be worth now?

This is based on house price inflation of 49.5%, between April 2007 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 49.5% inflationary increase is applied to the most recent sale price for 14 BLACKBROOK of £167,750 on 27th April 2007. For the value to have increased from £167,750 to £250,867 over the eighteen years and two months to February 2025, the following assumptions must hold true:

• The value of 14 BLACKBROOK has moved in line with the HPI for detached houses in the Merthyr Tydfil local authority area.
• The April 2007 sale price of £167,750 represented a fair market value for the property.
