1 CASTLEMILK 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 two 1 CASTLEMILK sales from September 2011 and March 2015 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 September 2011 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the March 2015 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 1 CASTLEMILK be worth now?

1 CASTLEMILK might now be worth an estimated £518,360.

This is based on house price inflation of 40.1%, between March 2015 and February 2025, 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 40.1% inflationary increase is applied to the most recent sale price for 1 CASTLEMILK of £370,000 on 27th March 2015. For the value to have increased from £370,000 to £518,360 over the ten years and one month to February 2025, the following assumptions must hold true:

• The value of 1 CASTLEMILK has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The March 2015 sale price of £370,000 represented a fair market value for the property.
• The size, condition, and specification of 1 CASTLEMILK has not materially changed since March 2015.
