WARREN HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Lewes local authority area over time, sourced from the HPI. The two WARREN HOUSE sales from June 1999 and September 2016 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 June 1999 sale was for 264% above the HPI. So the extrapolation line tracks at 264% above the HPI over time, until the September 2016 sale, where it falls to 132% above the HPI. The line then continues to track at 132% above the HPI.

What might WARREN HOUSE be worth now?

WARREN HOUSE might now be worth an estimated £1,357,766.

This is based on house price inflation of 20.7%, between September 2016 and December 2024, for detached houses, in the Lewes local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 20.7% inflationary increase is applied to the most recent sale price for WARREN HOUSE of £1,125,000 on 6th September 2016. For the value to have increased from £1,125,000 to £1,357,766 over the seven years and nine months to December 2024, the following assumptions must hold true:

• The value of WARREN HOUSE has moved in line with the HPI for detached houses in the Lewes local authority area.
• The September 2016 sale price of £1,125,000 represented a fair market value for the property.
• The size, condition, and specification of WARREN HOUSE has not materially changed since September 2016.
