We have seen how NIB operates. IF they decided to look at LTV’s there would be no consultation. Customers would receive a letter informing them that their LTV was now below XX%, in line with your T&c’s the applicable interest rate will now be the home loan rate of XX%. Your new repayment will be €XXXX.XX from the XX/XX/XXXX.
The new increased payment would be taken from your account thereafter. Your only option would be to follow the complaints procedure which would eventually end up on the Ombudsman’s desk.
I don’t think the above scenario can be ruled out.
