11 BLACKSTONE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Swindon local authority area over time, sourced from the HPI. The two 11 BLACKSTONE AVENUE sales from February 1999 and July 2015 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 1999 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the July 2015 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 11 BLACKSTONE AVENUE be worth now?

This is based on house price inflation of 53%, between July 2015 and June 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 53% inflationary increase is applied to the most recent sale price for 11 BLACKSTONE AVENUE of £193,000 on 10th July 2015. For the value to have increased from £193,000 to £295,196 over the ten years and one month to June 2025, the following assumptions must hold true:
