The below graph shows the average terraced house price in the Bridgend local authority area over time, sourced from the HPI. The three 15 MARY STREET sales between November 1998 and August 2014 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 2001 sale was for 179% above the HPI. So the extrapolation line tracks at 179% above the HPI over time, until the August 2014 sale, where it falls to 160% above the HPI. The line then continues to track at 160% above the HPI.

15 MARY STREET might now be worth an estimated £435,543.
This is based on house price inflation of 76%, between August 2014 and July 2025, for terraced houses, in the Bridgend local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
