31 HEOL Y WAUN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The four 31 HEOL Y WAUN sales between February 1995 and March 2016 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 February 2008 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the March 2016 sale, where it rises to 96% above the HPI. The line then continues to track at 96% above the HPI.

What might 31 HEOL Y WAUN be worth now?

31 HEOL Y WAUN might now be worth an estimated £1,013,160.

This is based on house price inflation of 42.7%, between March 2016 and June 2025, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 42.7% inflationary increase is applied to the most recent sale price for 31 HEOL Y WAUN of £710,000 on 23rd March 2016. For the value to have increased from £710,000 to £1,013,160 over the eight years and nine months to June 2025, the following assumptions must hold true:

  • The value of 31 HEOL Y WAUN has moved in line with the HPI for detached houses in the Cardiff local authority area.
  • The March 2016 sale price of £710,000 represented a fair market value for the property.
  • The size, condition, and specification of 31 HEOL Y WAUN has not materially changed since March 2016.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
