The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The three 15 CLOS Y GWALCH sales between December 1996 and March 2011 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 2004 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the March 2011 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.
15 CLOS Y GWALCH might now be worth an estimated £264,206.
This is based on house price inflation of 88.7%, between March 2011 and June 2025, for terraced 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 88.7% inflationary increase is applied to the most recent sale price for 15 CLOS Y GWALCH of £140,000 on 3rd March 2011. For the value to have increased from £140,000 to £264,206 over the thirteen years and nine months to June 2025, the following assumptions must hold true:
