19 GLENBOI 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 three 19 GLENBOI sales between January 2010 and July 2017 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 August 2011 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the July 2017 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 19 GLENBOI be worth now?

19 GLENBOI might now be worth an estimated £253,307.

This is based on house price inflation of 53.5%, between July 2017 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 53.5% inflationary increase is applied to the most recent sale price for 19 GLENBOI of £164,995 on 21st July 2017. For the value to have increased from £164,995 to £253,307 over the eight years and five months to February 2025, the following assumptions must hold true:

• The value of 19 GLENBOI has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The July 2017 sale price of £164,995 represented a fair market value for the property.
