21 LLANGYNIDR ROAD 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 21 LLANGYNIDR ROAD sales from November 2001 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 November 2001 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the August 2010 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 21 LLANGYNIDR ROAD be worth now?

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 LLANGYNIDR ROAD of £171,000 on 27th August 2010. For the value to have increased from £171,000 to £311,507 over the fifteen years and two months to June 2025, the following assumptions must hold true:

• The value of 21 LLANGYNIDR ROAD has moved in line with the HPI for semi-detached houses in the Cardiff local authority area.
• The August 2010 sale price of £171,000 represented a fair market value for the property.
