The below graph shows the average terraced house price in the Gloucester local authority area over time, sourced from the HPI. The seven 21 KNOWLES ROAD sales between June 1997 and January 2023 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 February 2019 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the January 2023 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

21 KNOWLES ROAD might now be worth an estimated £240,644.
This is based on house price inflation of 3%, between January 2023 and April 2026, for terraced houses, in the Gloucester local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 3% inflationary increase is applied to the most recent sale price for 21 KNOWLES ROAD of £233,700 on 17th January 2023. For the value to have increased from £233,700 to £240,644 over the two years and nine months to April 2026, the following assumptions must hold true:
