DERWYN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the New Forest local authority area over time, sourced from the HPI. The two DERWYN sales from May 2020 and May 2022 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 May 2020 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the May 2022 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might DERWYN be worth now?

DERWYN might now be worth an estimated £310,179.

This is based on house price deflation of 3.1%, between May 2022 and February 2025, for semi-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 3.1% deflationary decrease is applied to the most recent sale price for DERWYN of £320,000 on 20th May 2022. For the value to have decreased from £320,000 to £310,179 over the three years and three months to February 2025, the following assumptions must hold true:

• The value of DERWYN has moved in line with the HPI for semi-detached houses in the New Forest local authority area.
• The May 2022 sale price of £320,000 represented a fair market value for the property.
• The size, condition, and specification of DERWYN has not materially changed since May 2022.
