The below graph shows the average terraced house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The four 20 BROOK STREET sales between September 2010 and June 2015 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 October 2012 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the June 2015 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.

20 BROOK STREET might now be worth an estimated £118,091.

The 76.3% inflationary increase is applied to the most recent sale price for 20 BROOK STREET of £67,000 on 30th June 2015. For the value to have increased from £67,000 to £118,091 over the nine years and eleven months to July 2025, the following assumptions must hold true:
