The figures are based on a repayment mortgage .

When you are working out if you can afford to pay a mortgage  – you should consider if you could  afford to keep up the monthly repayments if your income was to fall or your outgoings increased.

Adding 5 years to a mortgage term (30 years instead of 25) – will reduce the monthly payments but it will increase the total amount you repay overall.

For example – on a €250k mortgage at 3% over 25 years you will end up paying €105,658 in interest on top of the €250,000 capital.

If you extend this to repay over 30 years you will end up paying €129,444 in interest on top of the €250,000 capital. That’s an extra €23,786 !

On the Bank of Ireland website they have a mortgage calculator where you can see how much you might be able to borrow and exactly what your monthly payments would be.

Repayment Mortgages – the monthly repayment is made up of two parts: An interest payment on the loan and a  capital repayment  . At the end of the mortgage term you will have paid in full for the house.  In the early years, most of your repayments will go toward paying off the interest on your mortgage. But as your mortgage reduces, the interest part of the repayment goes down. So as time goes on, more of your monthly repayments go toward paying off the capital.
