15 CEFN COCH 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 three 15 CEFN COCH sales between August 2000 and December 2005 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 2004 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the December 2005 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 15 CEFN COCH be worth now?

15 CEFN COCH might now be worth an estimated £287,709.

This is based on house price inflation of 89.3%, between December 2005 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 89.3% inflationary increase is applied to the most recent sale price for 15 CEFN COCH of £152,000 on 9th December 2005. For the value to have increased from £152,000 to £287,709 over the twenty years and six months to June 2025, the following assumptions must hold true:

• The value of 15 CEFN COCH has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
• The December 2005 sale price of £152,000 represented a fair market value for the property.
• The size, condition, and specification of 15 CEFN COCH has not materially changed since December 2005.
