3 CASTLEFIELDS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The six 3 CASTLEFIELDS sales between March 1995 and September 2019 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 2019 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the September 2019 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 3 CASTLEFIELDS be worth now?

3 CASTLEFIELDS might now be worth an estimated £604,990.

This is based on house price inflation of 15.2%, between September 2019 and April 2026, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 15.2% inflationary increase is applied to the most recent sale price for 3 CASTLEFIELDS of £525,000 on 25th September 2019. For the value to have increased from £525,000 to £604,990 over the seven years and five months to April 2026, the following assumptions must hold true:

• The value of 3 CASTLEFIELDS has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The September 2019 sale price of £525,000 represented a fair market value for the property.
• The size, condition, and specification of 3 CASTLEFIELDS has not materially changed since September 2019.
