31 HEOL CYNWRIG Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The two 31 HEOL CYNWRIG sales from October 2021 and October 2025 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 October 2021 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the October 2025 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 31 HEOL CYNWRIG be worth now?

This is based on house price inflation of 1.4%, between October 2025 and May 2026, for terraced 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 1.4% inflationary increase is applied to the most recent sale price for 31 HEOL CYNWRIG of £300,000 on 14th October 2025. For the value to have increased from £300,000 to £304,288 over the one year and five months to May 2026, the following assumptions must hold true:

• The October 2025 sale price of £300,000 represented a fair market value for the property.
