I think we need to examine the balance sheet closely to understand what type of debt and why use debt. The key to manage debt is duration: how to match your debt duration with your cashflow. I am going to borrow Gordon Gecko’s famous quote with a twist:
Debt for a lack of better word is good...
For personal debt with short term maturity such as credit card (revolving credit), has the following nature:
Current Liability
1. Short maturity - due in 30 days or less
2. 0% interest rate within 30 days or less
3. High interest once you roll it over into balance
4. Convenient payment solution with traceability
In most situation, you would use CC as your recurring expenses that you can pay it off on your monthly income/cashflow.
Fixed Liability
For mortgage debt that has a long term maturity (25-30years), it helps to alleviate your cash outlay if you use it right. This is where debt becomes beautiful:
1. Allows you to take control of a potentially appreciating asset with possible of cash flow
2. If debt’s interest rate does not catch up with inflation, then lender loses money. Imagine if you have a mortgage rate at 3% and annual inflation rate is 2%, lender only makes a 1% spread, while your asset appreciates 2% per year. Your holding cost is simply 1% without factoring principle repayment and cash flow generated from the rental
If you are able to manage the duration well, then piling debt is not burdensome. A lot of RE investors piled on debt without cashflow to suffice the debt obligation in order to bet on huge appreciation, which is gambling. You are better off betting #36 on the roulette table.
Again, think about all the sovereign debts for the moment. They never pay back the principal but kept refinancing it while they print more fiat money to create inflation. The more inflation they created, the cheaper their debt would be.
