I don't mind debt when its tax efficient
I have investments with a fixed income that earn more than my mortgage costs.
In fact, its a 3 to 1 ratio, so say my mortgage is $300k, that means I only need $100k of investment that pays the mortgage cost.
So I would be silly to take $300k of savings and use it to pay a $300k mortgage when just $100k of savings is earning enough to pay the $300k mortgage.
Same thing with car loans. I had enough cash to buy my Mercedes but they were offering 1.99% interest.
So long as your dont live beyond your means, and invest, borrowing can save you money. In fact, its what the very rich have been doing for a long time on many ways.
