The below table shows the price paid for the two sales, along with the average detached price in the Rhondda Cynon Taf local authority area for the corresponding sale date.

| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2011 22 SEP | £170,000 | £144,944 | 17% above HPI |
2003 18 DEC | £132,000 | £102,256 | 29% above HPI |
The below graph shows the average detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 91 MOUNTAIN VIEW sales from December 2003 and September 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 December 2003 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the September 2011 sale, where it falls to 17% above the HPI. The line then continues to track at 17% above the HPI.

91 MOUNTAIN VIEW might now be worth an estimated £340,909.
This is based on house price inflation of 100.5%, between September 2011 and April 2026, for detached houses, in the Rhondda Cynon Taf local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 100.5% inflationary increase is applied to the most recent sale price for 91 MOUNTAIN VIEW of £170,000 on 22nd September 2011. For the value to have increased from £170,000 to £340,909 over the fifteen years and five months to April 2026, the following assumptions must hold true:
