12 MAES GLAS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two 12 MAES GLAS sales from June 1996 and March 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 June 1996 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the March 2017 sale, where it rises to 33% above the HPI. The line then continues to track at 33% above the HPI.

What might 12 MAES GLAS be worth now?

12 MAES GLAS might now be worth an estimated £218,223.

This is based on house price inflation of 61.6%, between March 2017 and February 2025, for semi-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 61.6% inflationary increase is applied to the most recent sale price for 12 MAES GLAS of £135,000 on 30th March 2017. For the value to have increased from £135,000 to £218,223 over the eight years and one month to February 2025, the following assumptions must hold true:

• The value of 12 MAES GLAS has moved in line with the HPI for semi-detached houses in the Rhondda Cynon Taf local authority area.
• The March 2017 sale price of £135,000 represented a fair market value for the property.
