BLACKTHORN 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 BLACKTHORN sales from August 2006 and March 2020 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 August 2006 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the March 2020 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might BLACKTHORN be worth now?

BLACKTHORN might now be worth an estimated £1,105,699.

This is based on house price inflation of 14.9%, between March 2020 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 14.9% inflationary increase is applied to the most recent sale price for BLACKTHORN of £962,500 on 12th March 2020. For the value to have increased from £962,500 to £1,105,699 over the five years and one month to February 2025, the following assumptions must hold true:

  • The value of BLACKTHORN has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
  • The March 2020 sale price of £962,500 represented a fair market value for the property.
  • The size, condition, and specification of BLACKTHORN has not materially changed since March 2020.
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.
