Jane bought a house on 1 January 2012 for €250,000. If she sells the house on 1 January 2024, she will have owned the house for 12 years. 
Jane, in January 2024, might sell the house for €280,000 making a gain of €30,000. To calculate her partial relief, Jane will have to divided seven by 12 (number of years of ownership). She would then get relief on seven-twelfths (7/12) of the gain.
