20A ALPHA STREET Price Paid vs. HPI Average

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 20A ALPHA STREET sales from December 2010 and December 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 December 2010 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the December 2015 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 20A ALPHA STREET be worth now?

The 70.6% inflationary increase is applied to the most recent sale price for 20A ALPHA STREET of £185,000 on 4th December 2015. For the value to have increased from £185,000 to £315,543 over the nine years to December 2024, the following assumptions must hold true:
