The LTI limit restricts the amount of money you can borrow to a maximum of 4 times gross income for first-time-buyers and 3.5 times gross income for second/subsequent buyers.
So, for example, a first-time buyer couple with a combined income of €100,000 can borrow up to a maximum of €400,000.
A second and subsequent buyer with the same income can borrow up to a maximum of €350,000.
