Thu 06 Jun 2004He ain't heavy . . . he's my mortgageWould you describe your mortgage repayments as a heavy burden, somewhat of a burden, or no burden at all?If your answer is "no burden", then congratulations, because, like a third of people who responded to a recent survey on attitudes to debt, your direct debits to your lender are clearly 100 per cent free-flowing without any "insufficient funds" hiccups or knock-on effects on the rest of your household budget.
