19 MERLE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 19 MERLE AVENUE sales from March 2003 and May 2009 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 March 2003 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the May 2009 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 19 MERLE AVENUE be worth now?

19 MERLE AVENUE might now be worth an estimated £890,967.

This is based on house price inflation of 117.3%, between May 2009 and December 2024, for detached houses, in the Hillingdon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 117.3% inflationary increase is applied to the most recent sale price for 19 MERLE AVENUE of £410,000 on 27th May 2009. For the value to have increased from £410,000 to £890,967 over the fourteen years and five months to December 2024, the following assumptions must hold true:

• The May 2009 sale price of £410,000 represented a fair market value for the property.
