The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 1 ALLTMAWR ROAD sales from July 2000 and November 2016 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 July 2000 sale was for 80% above the HPI. So the extrapolation line tracks at 80% above the HPI over time, until the November 2016 sale, where it rises to 112% above the HPI. The line then continues to track at 112% above the HPI.
1 ALLTMAWR ROAD might now be worth an estimated £1,109,994.
This is based on house price inflation of 44.2%, between November 2016 and February 2025, for 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 44.2% inflationary increase is applied to the most recent sale price for 1 ALLTMAWR ROAD of £770,000 on 25th November 2016. For the value to have increased from £770,000 to £1,109,994 over the nine years and nine months to February 2025, the following assumptions must hold true:
