GRASSMOOR 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 GRASSMOOR sales between September 2000 and November 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 May 2018 sale was for 108% above the HPI. So the extrapolation line tracks at 108% above the HPI over time, until the November 2024 sale, where it rises to 117% above the HPI. The line then continues to track at 117% above the HPI.

What might GRASSMOOR be worth now?

GRASSMOOR might now be worth an estimated £620,774.

This is based on house price inflation of 5.2%, between November 2024 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 5.2% inflationary increase is applied to the most recent sale price for GRASSMOOR of £590,000 on 1st November 2024. For the value to have increased from £590,000 to £620,774 over the two years and seven months to April 2026, the following assumptions must hold true:

  • The value of GRASSMOOR has moved in line with the HPI for detached houses in the Cumberland local authority area.
  • The November 2024 sale price of £590,000 represented a fair market value for the property.
  • The size, condition, and specification of GRASSMOOR has not materially changed since November 2024.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
