ALDER HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dorset local authority area over time, sourced from the HPI. The two ALDER HOUSE sales from October 2019 and August 2025 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 2019 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the August 2025 sale, where it rises to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might ALDER HOUSE be worth now?

ALDER HOUSE might now be worth an estimated £475,682.

This is based on house price deflation of 0.9%, between August 2025 and May 2026, for detached houses, in the Dorset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.9% deflationary decrease is applied to the most recent sale price for ALDER HOUSE of £480,000 on 12th August 2025. For the value to have decreased from £480,000 to £475,682 over the one year and three months to May 2026, the following assumptions must hold true:

• The value of ALDER HOUSE has moved in line with the HPI for detached houses in the Dorset local authority area.
• The August 2025 sale price of £480,000 represented a fair market value for the property.
• The size, condition, and specification of ALDER HOUSE has not materially changed since August 2025.
