21 BAYDONS LANE 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 21 BAYDONS LANE sales from March 1999 and October 2018 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 March 1999 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the October 2018 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 21 BAYDONS LANE be worth now?

21 BAYDONS LANE might now be worth an estimated £476,968.

This is based on house price inflation of 17.8%, between October 2018 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 17.8% inflationary increase is applied to the most recent sale price for 21 BAYDONS LANE of £405,000 on 8th October 2018. For the value to have increased from £405,000 to £476,968 over the five years and ten months to December 2024, the following assumptions must hold true:

• The value of 21 BAYDONS LANE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The October 2018 sale price of £405,000 represented a fair market value for the property.
