41 SLAVE HILL 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 41 SLAVE HILL sales from December 1996 and June 2002 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 December 1996 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the June 2002 sale, where it rises to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 41 SLAVE HILL be worth now?

41 SLAVE HILL might now be worth an estimated £768,986.

This is based on house price inflation of 140.3%, between June 2002 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 140.3% inflationary increase is applied to the most recent sale price for 41 SLAVE HILL of £320,000 on 14th June 2002. For the value to have increased from £320,000 to £768,986 over the 21 years and six months to December 2024, the following assumptions must hold true:

• The value of 41 SLAVE HILL has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The June 2002 sale price of £320,000 represented a fair market value for the property.
