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 FARMLEIGH sales from September 2003 and September 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 September 2003 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2005 sale, which was also at 2% below the HPI.

21 FARMLEIGH might now be worth an estimated £320,404.
This is based on house price inflation of 92.5%, between September 2005 and May 2026, 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 92.5% inflationary increase is applied to the most recent sale price for 21 FARMLEIGH of £166,475 on 29th September 2005. For the value to have increased from £166,475 to £320,404 over the 21 years and four months to May 2026, the following assumptions must hold true:
