LANSDOWNE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two LANSDOWNE sales from September 2015 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 September 2015 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the February 2026 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might LANSDOWNE be worth now?

LANSDOWNE might now be worth an estimated £542,398.

This is based on house price deflation of 2.3%, between February 2026 and April 2026, for detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.3% deflationary decrease is applied to the most recent sale price for LANSDOWNE of £555,000 on 20th February 2026. For the value to have decreased from £555,000 to £542,398 over the ten months to April 2026, the following assumptions must hold true:

• The value of LANSDOWNE has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
• The February 2026 sale price of £555,000 represented a fair market value for the property.
• The size, condition, and specification of LANSDOWNE has not materially changed since February 2026.
