The below graph shows the average semi-detached house price in the Swindon local authority area over time, sourced from the HPI. The four 20 JEFFERIES AVENUE sales between March 1996 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 July 2010 sale was for 30% above the HPI. So the extrapolation line tracks at 30% above the HPI over time, until the August 2014 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.
20 JEFFERIES AVENUE might now be worth an estimated £407,746.
This is based on house price inflation of 63.1%, between August 2014 and February 2025, for semi-detached houses, in the Swindon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 63.1% inflationary increase is applied to the most recent sale price for 20 JEFFERIES AVENUE of £249,950 on 29th August 2014. For the value to have increased from £249,950 to £407,746 over the eleven years and six months to February 2025, the following assumptions must hold true:
