|---|---|---|---|

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The four 45 MILL ROAD sales between November 2001 and June 2018 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 May 2008 sale was for 230% above the HPI. So the extrapolation line tracks at 230% above the HPI over time, until the June 2018 sale, where it falls to 113% above the HPI. The line then continues to track at 113% above the HPI.

45 MILL ROAD might now be worth an estimated £1,107,463.
This is based on house price inflation of 35.1%, between June 2018 and May 2026, 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 35.1% inflationary increase is applied to the most recent sale price for 45 MILL ROAD of £820,000 on 14th June 2018. For the value to have increased from £820,000 to £1,107,463 over the eight years and one month to May 2026, the following assumptions must hold true:
