30 GROVE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Norfolk local authority area over time, sourced from the HPI. The three 30 GROVE AVENUE sales between May 1995 and July 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 March 2022 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the July 2025 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 30 GROVE AVENUE be worth now?
