18 PETTY 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 three 18 PETTY LANE sales between July 1999 and June 2016 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 June 2010 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the June 2016 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 18 PETTY LANE be worth now?

18 PETTY LANE might now be worth an estimated £597,699.

This is based on house price inflation of 32.8%, between June 2016 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 32.8% inflationary increase is applied to the most recent sale price for 18 PETTY LANE of £450,000 on 16th June 2016. For the value to have increased from £450,000 to £597,699 over the seven years and six months to December 2024, the following assumptions must hold true:

• The value of 18 PETTY LANE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The June 2016 sale price of £450,000 represented a fair market value for the property.
• The size, condition, and specification of 18 PETTY LANE has not materially changed since June 2016.
