15 FIRS CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 15 FIRS CLOSE sales from November 2012 and September 2013 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 November 2012 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the September 2013 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 15 FIRS CLOSE be worth now?

15 FIRS CLOSE might now be worth an estimated £657,105.

This is based on house price inflation of 56.5%, between September 2013 and February 2025, for detached houses, in the Wiltshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 56.5% inflationary increase is applied to the most recent sale price for 15 FIRS CLOSE of £420,000 on 11th September 2013. For the value to have increased from £420,000 to £657,105 over the twelve years and seven months to February 2025, the following assumptions must hold true:

• The value of 15 FIRS CLOSE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The September 2013 sale price of £420,000 represented a fair market value for the property.
• The size, condition, and specification of 15 FIRS CLOSE has not materially changed since September 2013.
