18 HEOL NANT CAIACH 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 six 18 HEOL NANT CAIACH sales between August 1999 and November 2018 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 November 2007 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the November 2018 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 18 HEOL NANT CAIACH be worth now?

18 HEOL NANT CAIACH might now be worth an estimated £241,643.

This is based on house price inflation of 34.2%, between November 2018 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 34.2% inflationary increase is applied to the most recent sale price for 18 HEOL NANT CAIACH of £179,995 on 8th November 2018. For the value to have increased from £179,995 to £241,643 over the seven years and nine months to February 2025, the following assumptions must hold true:

  • The value of 18 HEOL NANT CAIACH has moved in line with the HPI for detached houses in the Merthyr Tydfil local authority area.
  • The November 2018 sale price of £179,995 represented a fair market value for the property.
  • The size, condition, and specification of 18 HEOL NANT CAIACH has not materially changed since November 2018.
