BELLAIRE Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The two BELLAIRE sales from April 2019 and September 2023 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 2019 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the September 2023 sale, where it rises to 125% above the HPI. The line then continues to track at 125% above the HPI.

What might BELLAIRE be worth now?

BELLAIRE might now be worth an estimated £531,242.

This is based on house price inflation of 9.5%, between September 2023 and February 2025, for detached houses, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9.5% inflationary increase is applied to the most recent sale price for BELLAIRE of £485,000 on 1st September 2023. For the value to have increased from £485,000 to £531,242 over the two years and seven months to February 2025, the following assumptions must hold true:

• The value of BELLAIRE has moved in line with the HPI for detached houses in the County Durham local authority area.
• The September 2023 sale price of £485,000 represented a fair market value for the property.
• The size, condition, and specification of BELLAIRE has not materially changed since September 2023.
