Read the article I posted above. If the OP decides to move to the UK then he/she will not be able to return to live in Ireland for many a year because the banks here will pursue her for the amount owed. She and her partner owe well in excess of €300,000 and her earnings of €18000 can not and will not service that sort of debt. It works out at over 15 times the OP annual salary.
The figures just dont add up and you can't get blood from a stone. I wish the couple well.
