40 COMET STREET 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 three 40 COMET STREET sales between August 1999 and March 2020 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 2002 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the March 2020 sale, where it falls to 52% below the HPI. The line then continues to track at 52% below the HPI.

What might 40 COMET STREET be worth now?

40 COMET STREET might now be worth an estimated £248,007.

This is based on house price inflation of 28.8%, between March 2020 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 28.8% inflationary increase is applied to the most recent sale price for 40 COMET STREET of £192,600 on 6th March 2020. For the value to have increased from £192,600 to £248,007 over the four years and nine months to June 2025, the following assumptions must hold true:

  • The value of 40 COMET STREET has moved in line with the HPI for detached houses in the Cardiff local authority area.
  • The March 2020 sale price of £192,600 represented a fair market value for the property.
  • The size, condition, and specification of 40 COMET STREET has not materially changed since March 2020.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
