10 WENTLOOG RISE 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 10 WENTLOOG RISE sales from November 2005 and March 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 November 2005 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the March 2026 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 10 WENTLOOG RISE be worth now?

10 WENTLOOG RISE might now be worth an estimated £423,919.

This is based on house price inflation of 0.9%, between March 2026 and April 2026, 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 0.9% inflationary increase is applied to the most recent sale price for 10 WENTLOOG RISE of £420,000 on 9th March 2026. For the value to have increased from £420,000 to £423,919 over the eleven months to April 2026, the following assumptions must hold true:

• The value of 10 WENTLOOG RISE has moved in line with the HPI for detached houses in the Newport local authority area.
• The March 2026 sale price of £420,000 represented a fair market value for the property.
