11 PORTMARNOCK WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the South Kesteven local authority area over time, sourced from the HPI. The three 11 PORTMARNOCK WAY sales between August 2005 and January 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 November 2008 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the January 2018 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 11 PORTMARNOCK WAY be worth now?

11 PORTMARNOCK WAY might now be worth an estimated £203,000.

This is based on house price inflation of 32.2%, between January 2018 and March 2025, for semi-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 32.2% inflationary increase is applied to the most recent sale price for 11 PORTMARNOCK WAY of £153,500 on 26th January 2018. For the value to have increased from £153,500 to £203,000 over the six years and ten months to March 2025, the following assumptions must hold true:

• The value of 11 PORTMARNOCK WAY has moved in line with the HPI for semi-detached houses in the South Kesteven local authority area.
• The January 2018 sale price of £153,500 represented a fair market value for the property.
