18 CARNARVON 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 three 18 CARNARVON CLOSE sales between March 2006 and April 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 September 2007 sale was for 45% below the HPI. So the extrapolation line tracks at 45% below the HPI over time, until the April 2016 sale, where it rises to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 18 CARNARVON CLOSE be worth now?

18 CARNARVON CLOSE might now be worth an estimated £317,144.

This is based on house price inflation of 32.1%, between April 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 32.1% inflationary increase is applied to the most recent sale price for 18 CARNARVON CLOSE of £240,000 on 29th April 2016. For the value to have increased from £240,000 to £317,144 over the seven years and four months to December 2024, the following assumptions must hold true:

• The value of 18 CARNARVON CLOSE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The April 2016 sale price of £240,000 represented a fair market value for the property.
