9 GROES LON Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 9 GROES LON sales from December 2011 and September 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 2011 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the September 2024 sale, where it rises to 71% above the HPI. The line then continues to track at 71% above the HPI.

What might 9 GROES LON be worth now?

9 GROES LON might now be worth an estimated £544,870.

This is based on house price inflation of 1.1%, between September 2024 and June 2025, for semi-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 1.1% inflationary increase is applied to the most recent sale price for 9 GROES LON of £539,000 on 19th September 2024. For the value to have increased from £539,000 to £544,870 over the one year and three months to June 2025, the following assumptions must hold true:
