TONGERLO 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 TONGERLO sales from February 1997 and December 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 February 1997 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the December 2020 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.

What might TONGERLO be worth now?

TONGERLO might now be worth an estimated £432,801.

This is based on house price inflation of 8.2%, between December 2020 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 8.2% inflationary increase is applied to the most recent sale price for TONGERLO of £400,000 on 18th December 2020. For the value to have increased from £400,000 to £432,801 over the four years to December 2024, the following assumptions must hold true:

• The value of TONGERLO has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The December 2020 sale price of £400,000 represented a fair market value for the property.
• The size, condition, and specification of TONGERLO has not materially changed since December 2020.
