41 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 41 GLENBOI sales between June 2003 and September 2022 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 July 2014 sale was for 53% above the HPI. So the extrapolation line tracks at 53% above the HPI over time, until the September 2022 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might 41 GLENBOI be worth now?

41 GLENBOI might now be worth an estimated £358,271.

This is based on house price inflation of 0.9%, between September 2022 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 0.9% inflationary increase is applied to the most recent sale price for 41 GLENBOI of £355,000 on 16th September 2022. For the value to have increased from £355,000 to £358,271 over the three years and seven months to February 2025, the following assumptions must hold true:

• The value of 41 GLENBOI has moved in line with the HPI for detached houses in the Rhondda Cynon Taf local authority area.
• The September 2022 sale price of £355,000 represented a fair market value for the property.
