16 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 16 BOI CLOSE sales from September 2017 and July 2019 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 September 2017 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the July 2019 sale, which was also at 32% below the HPI.

What might 16 BOI CLOSE be worth now?

This is based on house price inflation of 38.9%, between July 2019 and February 2025, 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 38.9% inflationary increase is applied to the most recent sale price for 16 BOI CLOSE of £131,000 on 19th July 2019. For the value to have increased from £131,000 to £181,915 over the six years and five months to February 2025, the following assumptions must hold true:
