GLENLION 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 GLENLION sales from April 2000 and April 2022 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 2000 sale was for 102% above the HPI. So the extrapolation line tracks at 102% above the HPI over time, until the April 2022 sale, where it falls to 92% above the HPI. The line then continues to track at 92% above the HPI.

What might GLENLION be worth now?

GLENLION might now be worth an estimated £1,598,390.

This is based on house price inflation of 3.1%, between April 2022 and December 2024, 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 3.1% inflationary increase is applied to the most recent sale price for GLENLION of £1,550,000 on 22nd April 2022. For the value to have increased from £1,550,000 to £1,598,390 over the one year and four months to December 2024, the following assumptions must hold true:

• The value of GLENLION has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The April 2022 sale price of £1,550,000 represented a fair market value for the property.
• The size, condition, and specification of GLENLION has not materially changed since April 2022.
