6 IRWIN GROVE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Basingstoke and Deane local authority area over time, sourced from the HPI. The two 6 IRWIN GROVE sales from June 2021 and December 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 June 2021 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the December 2025 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 6 IRWIN GROVE be worth now?

6 IRWIN GROVE might now be worth an estimated £439,294.

This is based on house price deflation of 2.4%, between December 2025 and April 2026, for semi-detached houses, in the Basingstoke and Deane local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.4% deflationary decrease is applied to the most recent sale price for 6 IRWIN GROVE of £450,000 on 19th December 2025. For the value to have decreased from £450,000 to £439,294 over the one year and eight months to April 2026, the following assumptions must hold true:

• The value of 6 IRWIN GROVE has moved in line with the HPI for semi-detached houses in the Basingstoke and Deane local authority area.
• The December 2025 sale price of £450,000 represented a fair market value for the property.
