TAMBORA Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bracknell Forest local authority area over time, sourced from the HPI. The two TAMBORA sales from May 2006 and December 2015 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 May 2006 sale was for 79% above the HPI. So the extrapolation line tracks at 79% above the HPI over time, until the December 2015 sale, where it rises to 178% above the HPI. The line then continues to track at 178% above the HPI.

What might TAMBORA be worth now?

TAMBORA might now be worth an estimated £2,077,081.

This is based on house price inflation of 25.3%, between December 2015 and December 2024, for detached houses, in the Bracknell Forest local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 25.3% inflationary increase is applied to the most recent sale price for TAMBORA of £1,657,500 on 2nd December 2015. For the value to have increased from £1,657,500 to £2,077,081 over the nine years to December 2024, the following assumptions must hold true:

• The value of TAMBORA has moved in line with the HPI for detached houses in the Bracknell Forest local authority area.
• The December 2015 sale price of £1,657,500 represented a fair market value for the property.
• The size, condition, and specification of TAMBORA has not materially changed since December 2015.
