MORTIMER HOUSE 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 three MORTIMER HOUSE sales between February 1997 and February 2025 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 2013 sale was for 138% above the HPI. So the extrapolation line tracks at 138% above the HPI over time, until the February 2025 sale, where it falls to 126% above the HPI. The line then continues to track at 126% above the HPI.

What might MORTIMER HOUSE be worth now?

MORTIMER HOUSE might now be worth an estimated £1,926,640.

This is based on house price deflation of 1.2%, between February 2025 and April 2026, 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 1.2% deflationary decrease is applied to the most recent sale price for MORTIMER HOUSE of £1,950,000 on 12th February 2025. For the value to have decreased from £1,950,000 to £1,926,640 over the ten months to April 2026, the following assumptions must hold true:

• The value of MORTIMER HOUSE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The February 2025 sale price of £1,950,000 represented a fair market value for the property.
