TREE TOPS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cumberland local authority area over time, sourced from the HPI. The four TREE TOPS sales between November 1998 and July 2025 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 October 2024 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the July 2025 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might TREE TOPS be worth now?

TREE TOPS might now be worth an estimated £412,717.

This is based on house price inflation of 3.8%, between July 2025 and April 2026, for detached houses, in the Cumberland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.8% inflationary increase is applied to the most recent sale price for TREE TOPS of £397,500 on 31st July 2025. For the value to have increased from £397,500 to £412,717 over the one year and three months to April 2026, the following assumptions must hold true:

• The value of TREE TOPS has moved in line with the HPI for detached houses in the Cumberland local authority area.
• The July 2025 sale price of £397,500 represented a fair market value for the property.
• The size, condition, and specification of TREE TOPS has not materially changed since July 2025.
