WALNUT TREE HOUSE 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 WALNUT TREE HOUSE sales from July 2013 and October 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 July 2013 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the October 2024 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might WALNUT TREE HOUSE be worth now?

WALNUT TREE HOUSE might now be worth an estimated £530,630.

This is based on house price inflation of 3%, between October 2024 and June 2025, 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 3% inflationary increase is applied to the most recent sale price for WALNUT TREE HOUSE of £515,000 on 10th October 2024. For the value to have increased from £515,000 to £530,630 over the one year and four months to June 2025, the following assumptions must hold true:

• The value of WALNUT TREE HOUSE has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
• The October 2024 sale price of £515,000 represented a fair market value for the property.
• The size, condition, and specification of WALNUT TREE HOUSE has not materially changed since October 2024.
