TWIN ALDERS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three TWIN ALDERS sales between April 2003 and July 2018 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 September 2013 sale was for 71% above the HPI. So the extrapolation line tracks at 71% above the HPI over time, until the July 2018 sale, where it rises to 91% above the HPI. The line then continues to track at 91% above the HPI.

What might TWIN ALDERS be worth now?

TWIN ALDERS might now be worth an estimated £591,438.

This is based on house price inflation of 53.6%, between July 2018 and December 2024, for detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 53.6% inflationary increase is applied to the most recent sale price for TWIN ALDERS of £385,000 on 5th July 2018. For the value to have increased from £385,000 to £591,438 over the five years and seven months to December 2024, the following assumptions must hold true:

• The value of TWIN ALDERS has moved in line with the HPI for detached houses in the Caerphilly local authority area.
• The July 2018 sale price of £385,000 represented a fair market value for the property.
• The size, condition, and specification of TWIN ALDERS has not materially changed since July 2018.
