LAMPHEYS 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 LAMPHEYS sales from August 2015 and April 2021 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 2015 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the April 2021 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might LAMPHEYS be worth now?

LAMPHEYS might now be worth an estimated £658,706.

This is based on house price inflation of 12.1%, between April 2021 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 12.1% inflationary increase is applied to the most recent sale price for LAMPHEYS of £587,500 on 23rd April 2021. For the value to have increased from £587,500 to £658,706 over the two years and four months to December 2024, the following assumptions must hold true:

• The value of LAMPHEYS has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The April 2021 sale price of £587,500 represented a fair market value for the property.
• The size, condition, and specification of LAMPHEYS has not materially changed since April 2021.
