Simply prove to your chosen bank your capability to repay the loan. If the repayments will be over €1475 per month, then you would need to satisfy them that it will not put you at a financial disadvantage.
To do this you would need to be saving a minimum of €1750 per month or paying a combined rent and savings to bring you up to about that amount.
The reason why I say €1750 per month is that you need to pass the bank's stress test in relation to a rise in interest rates, and you also need to allow for insurances.
That is a massive chunk out of your disposable income btw, and will put you under a huge amount of stress.
