27 PORTMARNOCK WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Kesteven local authority area over time, sourced from the HPI. The four 27 PORTMARNOCK WAY sales between November 2005 and August 2024 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 August 2017 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the August 2024 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 27 PORTMARNOCK WAY be worth now?

This is based on house price inflation of 2.1%, between August 2024 and December 2024, for detached houses, in the South Kesteven local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.1% inflationary increase is applied to the most recent sale price for 27 PORTMARNOCK WAY of £270,000 on 16th August 2024. For the value to have increased from £270,000 to £275,686 over the eight months to December 2024, the following assumptions must hold true:

• The value of 27 PORTMARNOCK WAY has moved in line with the HPI for detached houses in the South Kesteven local authority area.
• The August 2024 sale price of £270,000 represented a fair market value for the property.
