ROSELEIGH 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 ROSELEIGH sales from February 1998 and May 2000 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 February 1998 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the May 2000 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might ROSELEIGH be worth now?

ROSELEIGH might now be worth an estimated £535,279.

This is based on house price inflation of 296.5%, between May 2000 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 296.5% inflationary increase is applied to the most recent sale price for ROSELEIGH of £135,000 on 15th May 2000. For the value to have increased from £135,000 to £535,279 over the 26 years and one month to April 2026, the following assumptions must hold true:

• The value of ROSELEIGH has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
• The May 2000 sale price of £135,000 represented a fair market value for the property.
• The size, condition, and specification of ROSELEIGH has not materially changed since May 2000.
