4 THIRLMERE PARK Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Westmorland and Furness local authority area over time, sourced from the HPI. The two 4 THIRLMERE PARK sales from April 1997 and September 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 April 1997 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the September 2025 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 4 THIRLMERE PARK be worth now?

4 THIRLMERE PARK might now be worth an estimated £236,213.

This is based on house price inflation of 2.3%, between September 2025 and October 2025, for semi-detached houses, in the Westmorland and Furness local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.3% inflationary increase is applied to the most recent sale price for 4 THIRLMERE PARK of £231,000 on 12th September 2025. For the value to have increased from £231,000 to £236,213 over the eleven months to October 2025, the following assumptions must hold true:

• The value of 4 THIRLMERE PARK has moved in line with the HPI for semi-detached houses in the Westmorland and Furness local authority area.
• The September 2025 sale price of £231,000 represented a fair market value for the property.
