30 ROUNDTOWN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The six 30 ROUNDTOWN sales between November 1995 and November 2024 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 2008 sale was for 165% above the HPI. So the extrapolation line tracks at 165% above the HPI over time, until the November 2024 sale, where it falls to 110% above the HPI. The line then continues to track at 110% above the HPI.

What might 30 ROUNDTOWN be worth now?

30 ROUNDTOWN might now be worth an estimated £604,833.

This is based on house price inflation of 4.3%, between November 2024 and August 2025, for semi-detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.3% inflationary increase is applied to the most recent sale price for 30 ROUNDTOWN of £580,000 on 29th November 2024. For the value to have increased from £580,000 to £604,833 over the one year and three months to August 2025, the following assumptions must hold true:
