6 DIANA GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Newport local authority area over time, sourced from the HPI. The two 6 DIANA GROVE sales from July 2017 and September 2022 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 2017 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the September 2022 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 6 DIANA GROVE be worth now?

6 DIANA GROVE might now be worth an estimated £432,050.

This is based on house price inflation of 2.9%, between September 2022 and June 2025, for detached houses, in the Newport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.9% inflationary increase is applied to the most recent sale price for 6 DIANA GROVE of £420,000 on 1st September 2022. For the value to have increased from £420,000 to £432,050 over the three years and three months to June 2025, the following assumptions must hold true:

  • The value of 6 DIANA GROVE has moved in line with the HPI for detached houses in the Newport local authority area.
  • The September 2022 sale price of £420,000 represented a fair market value for the property.
  • The size, condition, and specification of 6 DIANA GROVE has not materially changed since September 2022.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
