- 01Good debt generates income or builds assets — a mortgage on a cash-flowing rental property is the clearest example of debt working for you
- 02Bad debt finances consumption and depreciating assets — $25,000 in credit card debt at 24% APR costs over $12,000 in interest with minimum payments alone
- 03Jonathan controlled a $366,666 duplex with $36,666 down and nets $260/month in positive cash flow — that's leverage turning debt into wealth
- 04The one question that separates good debt from bad: does this debt generate income or build an asset that appreciates?

I'm Martin Maxwell. Robert Kiyosaki wrote something in Rich Dad Poor Dad that reshaped how I think about money: "An asset puts money in your pocket. A liability takes money out." That single line is the foundation for everything in this episode.
Debt isn't inherently good or bad. It's a tool — like a hammer that can build a house or break a window. Today we're looking at two real people who used debt in opposite directions. One built a cash-flowing investment. The other dug a $25,000 hole.
Jonathan's Duplex: Good Debt in Action
Jonathan Lee is a marketing professional who wanted to diversify his income. He found a duplex priced at $366,666 near a university and major employers — the kind of location where tenant demand stays strong year-round.
The numbers: Jonathan put down $36,666 (10% of the purchase price) and financed the remaining $330,000 with a 30-year fixed-rate mortgage. His monthly carrying costs — mortgage, taxes, insurance, and maintenance — came to $2,860. He rented both units at $2,600 each, pulling in $5,200/month. After expenses, he nets $260/month in positive cash flow.
That's roughly 10-to-1 leverage. Jonathan used $36,666 of his own money to control a $366,666 asset — and the asset pays for itself, then pays him on top. Every month, while tenants pay down the mortgage and build his equity.
Other examples of good debt: an FHA loan at 3.5% down on your first house hack, a HELOC used to fund a value-add renovation, a business loan that scales your property management company. The common thread — every dollar borrowed is connected to something that produces income or appreciates.
Emily's Credit Cards: Bad Debt Exposed
Emily Johnson is a graphic designer who fell into a pattern that's painfully common. It started small — dinner at a nice restaurant, a designer jacket, a weekend trip. Each purchase felt manageable. But the balances crept up. Before she realized it: $25,000 in credit card debt across multiple accounts, with rates as high as 24% APR.
At 24% interest, minimum payments barely cover the interest charges. That $25,000 balance takes over 20 years to clear at minimums — and you end up paying north of $12,000 in interest alone. Emily was renting money to buy things that lost value the moment she bought them.
It got worse. She started using new cards to cover daily expenses — groceries, gas, utilities. Savings? Gone. Financial flexibility? Gone. The ability to invest? Nonexistent. That's bad debt stripped bare — no asset producing income on the other side, nothing but compounding interest eating her paycheck every month.
The One Question That Matters
When you're evaluating any debt decision, ask this: Does this debt generate income or build an asset that appreciates?
If yes — good debt. Do your due diligence and move forward. If no — bad debt. Pay it off or don't take it on.
A mortgage on a rental property that generates $260/month in cash flow? Good debt — an 8.5% cash-on-cash return on your invested capital. A $5,000 credit card balance from a vacation that's already over? Bad debt — compounding at 24% while the tan fades.
This isn't about avoiding debt entirely. Real estate investing is built on leverage — using other people's money to control assets worth more than your cash alone could buy. The skill is knowing which debt serves your wealth and which debt erodes it.
Your Action Step
Pull up every debt you carry — credit cards, car loans, student loans, mortgage, personal loans. Write down three things for each: the balance, the interest rate, and whether it generates income or builds an asset. Categorize each one as good or bad, then calculate how much your bad debt costs you per month in interest alone. That number is the monthly cash flow leak you need to plug before you invest with full confidence.

An FHA loan is a government-insured mortgage that lets qualified borrowers buy 1–4 unit properties with as little as 3.5% down — as long as they live in one unit as their primary residence for at least 12 months.
