27 CLOS THOMAS 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 27 CLOS THOMAS sales from December 2020 and March 2024 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 December 2020 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the March 2024 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 27 CLOS THOMAS be worth now?

This is based on house price inflation of 4.7%, between March 2024 and June 2025, 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).
