55 MORTIMER WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Test Valley local authority area over time, sourced from the HPI. The three 55 MORTIMER WAY sales between November 1999 and February 2026 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 2007 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the February 2026 sale, which was also at 17% below the HPI.

What might 55 MORTIMER WAY be worth now?

The 1.2% inflationary increase is applied to the most recent sale price for 55 MORTIMER WAY of £297,500 on 23rd February 2026. For the value to have increased from £297,500 to £301,045 over the ten months to April 2026, the following assumptions must hold true:
