20 BISHOP 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 five 20 BISHOP CLOSE sales between May 1999 and September 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 December 2015 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the September 2021 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 20 BISHOP CLOSE be worth now?

20 BISHOP CLOSE might now be worth an estimated £414,660.

This is based on house price inflation of 14.2%, between September 2021 and December 2024, 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 14.2% inflationary increase is applied to the most recent sale price for 20 BISHOP CLOSE of £363,000 on 30th September 2021. For the value to have increased from £363,000 to £414,660 over the two years and nine months to December 2024, the following assumptions must hold true:

• The value of 20 BISHOP CLOSE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The September 2021 sale price of £363,000 represented a fair market value for the property.
• The size, condition, and specification of 20 BISHOP CLOSE has not materially changed since September 2021.
