7 MARNE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southampton local authority area over time, sourced from the HPI. The four 7 MARNE ROAD sales between April 1998 and June 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 July 2000 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the June 2025 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 7 MARNE ROAD be worth now?

7 MARNE ROAD might now be worth an estimated £255,260.

This is based on house price deflation of 0.7%, between June 2025 and July 2025, for semi-detached houses, in the Southampton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.7% deflationary decrease is applied to the most recent sale price for 7 MARNE ROAD of £257,000 on 13th June 2025. For the value to have decreased from £257,000 to £255,260 over the eleven months to July 2025, the following assumptions must hold true:

• The value of 7 MARNE ROAD has moved in line with the HPI for semi-detached houses in the Southampton local authority area.
• The June 2025 sale price of £257,000 represented a fair market value for the property.
