Hello, Tim. In principle I agree with Bowlingbun - pay off existing debts before you take on new ones. But there can be many circumstances. Can you give us a little more information?
Have you still any outstanging debts and where? Credit cards? Ovefrdfrafts? Are you saddled with a debt that charges high interest and wanting to replace it with a lower interest loan (this would require security)? Are you in employment?
What is your caring situation? Does the home loan you want relate to this. Are you or your caree receiving any allowances you are entitled to?
If you give us a fuller picture we may be able to make suggestions.
