8 BOI CLOSE 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 8 BOI CLOSE sales from February 1999 and February 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 February 1999 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the February 2016 sale, where it falls to 41% below the HPI. The line then continues to track at 41% below the HPI.

What might 8 BOI CLOSE be worth now?

The 77.2% inflationary increase is applied to the most recent sale price for 8 BOI CLOSE of £96,000 on 26th February 2016. For the value to have increased from £96,000 to £170,154 over the nine years and ten months to April 2026, the following assumptions must hold true:
