BON AMI Price Paid vs. HPI Average

The below graph shows the average detached house price in the New Forest local authority area over time, sourced from the HPI. The two BON AMI sales from October 2009 and August 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 October 2009 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the August 2018 sale, where it rises to 24% below the HPI. The line then continues to track at 24% below the HPI.

What might BON AMI be worth now?

BON AMI might now be worth an estimated £440,370.

This is based on house price inflation of 14.4%, between August 2018 and February 2025, for detached houses, in the New Forest local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 14.4% inflationary increase is applied to the most recent sale price for BON AMI of £385,000 on 9th August 2018. For the value to have increased from £385,000 to £440,370 over the seven years and six months to February 2025, the following assumptions must hold true:

• The value of BON AMI has moved in line with the HPI for detached houses in the New Forest local authority area.
• The August 2018 sale price of £385,000 represented a fair market value for the property.
• The size, condition, and specification of BON AMI has not materially changed since August 2018.
