31 THORNBURY CLOSE 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 31 THORNBURY CLOSE sales from August 1997 and February 1999 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 August 1997 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the February 1999 sale, where it falls to 30% above the HPI. The line then continues to track at 30% above the HPI.

What might 31 THORNBURY CLOSE be worth now?

This is based on house price inflation of 382.8%, between February 1999 and March 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 382.8% inflationary increase is applied to the most recent sale price for 31 THORNBURY CLOSE of £86,500 on 5th February 1999. For the value to have increased from £86,500 to £417,658 over the 25 years and eleven months to March 2025, the following assumptions must hold true:
