9 TAIR ERW 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 two 9 TAIR ERW sales from June 2023 and February 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 June 2023 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the February 2025 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 9 TAIR ERW be worth now?

This is based on house price inflation of 0.9%, between February 2025 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 0.9% inflationary increase is applied to the most recent sale price for 9 TAIR ERW of £535,000 on 6th February 2025. For the value to have increased from £535,000 to £539,636 over the eight months to June 2025, the following assumptions must hold true:
