$('.PropertyInformationCommonStyles__costAmountCopy').each(function(index, element){
    var price_string = $(element).text();
    var price = price_string.replace(/\D/g,'');

    var house_income_required = Math.floor(price / 3.5);
    var house_deposit = Math.floor(price * 0.1);
    if(price > 222000){
        house_deposit += Math.floor((price - 222000) * 0.2);
    }

    $(element).html("<s>"+price_string+"</s> Deposit of €"+house_deposit+" and €"+house_income_required+" income required");
});

The script just converts the house prices on https://www.daft.ie into the deposit and income requirements specified by the central bank.
