CHALK HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Guildford local authority area over time, sourced from the HPI. The three CHALK HOUSE sales between January 2001 and March 2017 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 2007 sale was for 418% above the HPI. So the extrapolation line tracks at 418% above the HPI over time, until the March 2017 sale, where it falls to 262% above the HPI. The line then continues to track at 262% above the HPI.

What might CHALK HOUSE be worth now?

CHALK HOUSE might now be worth an estimated £3,398,408.

This is based on house price inflation of 19.2%, between March 2017 and February 2025, for detached houses, in the Guildford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 19.2% inflationary increase is applied to the most recent sale price for CHALK HOUSE of £2,850,000 on 17th March 2017. For the value to have increased from £2,850,000 to £3,398,408 over the eight years and one month to February 2025, the following assumptions must hold true:

• The value of CHALK HOUSE has moved in line with the HPI for detached houses in the Guildford local authority area.
• The March 2017 sale price of £2,850,000 represented a fair market value for the property.
• The size, condition, and specification of CHALK HOUSE has not materially changed since March 2017.
