The below graph shows the average semi-detached house price in the Newport local authority area over time, sourced from the HPI. The four 21 GLANWERN AVENUE sales between April 2000 and July 2021 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 2019 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the July 2021 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.
21 GLANWERN AVENUE might now be worth an estimated £268,772.
This is based on house price inflation of 19.5%, between July 2021 and March 2025, for semi-detached houses, in the Newport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
