21 BORAGE 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 four 21 BORAGE CLOSE sales between June 1999 and August 2010 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 May 2005 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the August 2010 sale, where it falls to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 21 BORAGE CLOSE be worth now?

21 BORAGE CLOSE might now be worth an estimated £346,119.

This is based on house price inflation of 82.2%, between August 2010 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 82.2% inflationary increase is applied to the most recent sale price for 21 BORAGE CLOSE of £190,000 on 6th August 2010. For the value to have increased from £190,000 to £346,119 over the fifteen years and two months to June 2025, the following assumptions must hold true:

• The value of 21 BORAGE CLOSE has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
• The August 2010 sale price of £190,000 represented a fair market value for the property.
