The 25-Year-Old Who Retired: How Cody Berman Built $500K in Three Years (And How You Can Too)

What Most People Get Wrong About Financial Independence

At 25 years old, Cody Berman was done working.

Not because he was lazy. Not because he inherited money. Not because he got lucky. He was done because he had $500,000 invested in the stock market, owned 11 rental units generating $3,700/month in passive income, and realized he never had to work another day in his life if he didn’t want to.

Now 30 and author of the bestselling book “Retire by 30,” Cody is showing thousands of people that the traditional path—college, job, retirement at 65—isn’t the only option. In fact, it might be the slowest one.

Here’s what I learned from him about building serious wealth before most people graduate college.

The Hook That Changes Everything: Seeing Other People Do It First

Most people don’t believe financial independence is possible until they see someone else do it.

That’s the real reason Cody succeeded where millions fail. At 19, he attended Camp FI (Financial Independence), a conference where real people—not theoretical gurus—shared their stories. He met people who quit their jobs in their 20s. He met people traveling the world on passive income.

Something clicked: “If they can do it, I can do it.”

This is the Roger Bannister effect. Before anyone ran a four-minute mile, it was considered impossible. The year after Bannister did it, eight other runners followed. Why? Not because they suddenly got faster. Because they saw it was possible.

The lesson: Most people quit before they start because they’ve never seen proof it’s doable. Find your proof. Find your Bannister. Surround yourself with people who’ve already done what you want to do.

The Big Three: Why Two-Thirds of Your Paycheck Disappears

Here’s where most people’s financial independence journey dies: the big three expenses.

Housing, transportation, and food make up 67% of the average American’s budget. Two-thirds. Gone.

This is the bottleneck that keeps people broke.

But here’s where Cody’s approach differs from the deprivation-based FIRE movement: he doesn’t say “cut everything.” He says “optimize strategically.”

When Cody lived in Boston, his friends were paying $2,500/month for apartments. Cody and his wife bought a house hack—a multi-unit property—and got paid $800/month to live there. That’s a $3,300 swing with barely a lifestyle change.

Before the house hack, he was paying $450/month for a bedroom shared with a roommate. Not deprivation. Just creative.

For transportation, he’s driven the same paid-off 2015 Nissan Frontier for years. Not to punish himself, but because his net worth has grown 20X since he stopped buying new cars. He’d rather spend money on travel and experiences.

For food, he still eats out and travels. He just does it smarter: ordering entrees to split instead of full meals. Pre-gaming at home before going out. Finding Airbnbs with kitchens in travel destinations.

The math: Year 1 income was $96,000. Expenses: $24,000. Gap: $72,000.

That gap is what separates the broke from the wealthy. And the gap doesn’t come from deprivation—it comes from optimization.

The Income Acceleration Strategy That Nobody Teaches

Most people think the path to wealth is climbing the corporate ladder: $50K → $60K → $75K → $100K over a decade.

That’s exponential growth for snails.

Cody realized something at 19 that most people never figure out: the people who make the most money don’t trade hours for dollars. They build things that pay them in perpetuity.

So instead of trying to go from $50K to $100K in a W-2 job (which takes years), he built scalable income streams.

Year 1: $96,000 earned (from side hustles and scalable businesses) Year 2: $192,000 earned (doubled because he focused on scale, not hours) Year 3: $403,000 earned (doubled again)

Same 24 hours in a day. Same $24,000 in expenses. But income that doubled year-over-year.

How? By avoiding hourly trading completely. Cody built digital products, purchased rental real estate, created online courses. Things that pay once and get paid repeatedly.

Compare this to someone trading time for money: if you make $50/hour and work 40 hours/week, you make roughly $100K/year. To double that, you need to work 80 hours/week or find a job that pays $100/hour. Both are nearly impossible.

But with scalable income? Your work compounds. You put in the work once. It pays forever.

The key insight: You cannot reach financial independence by trading time for money. You have to build things.

Why Side Hustles Matter (Even If You Make Only $5)

Most people dismiss side hustles because “$5 won’t change my life.”

Cody’s perspective is different. When he made his first $5 outside a W-2 job, something unlocked in his brain: “I don’t need a boss. I can earn money on my own.”

That psychological shift is worth more than the $5.

It’s the difference between: “I am dependent on my employer” and “I can create income if I need to.”

From that first $5, he scaled to $10, then $50, then thousands. But it started with believing it was possible.

The action: Start a side hustle. Doesn’t matter if it’s freelancing, selling digital products, or flipping items on eBay. Just prove to yourself that you can earn money without a boss.

The Mistake Everyone Makes: Lifestyle Inflation

This is where most people fail.

They get their first real paycheck—say $60K/year. For the first time in their life, they have money. So they immediately upgrade: $2,500/month apartment, $750/month car payment, eating out 5 nights a week.

Expenses match income. Gap equals zero. Financial independence becomes impossible.

Cody avoided this trap by making intentional choices early: house hacking instead of renting, keeping the paid-off car, being creative with food spending.

But here’s the part people miss: he wasn’t depriving himself. He was still traveling. Still going out. Still living a good life. He just optimized the big three and kept the $72K gap growing.

The biggest mistake he sees people make? Upgrading their life the moment their income increases.

The Partnership Strategy: Why Most Fail and How to Succeed

Cody has done something Dustin (and most investors) haven’t: built sustainable business partnerships.

His podcast co-host Justin: 7+ years together, 3+ million downloads His business partner Julie at Gold City Ventures: multiple millions in revenue His Airbnb partner Brooke Multiple real estate partnerships

Most partnerships fail because people partner with someone just like them. Two marketers trying to build a product. Two sales guys trying to run operations. They butt heads and collapse.

Cody’s rule: partner with people who fill your weakness gaps.

If you’re a visionary but terrible at operations, find an operator. If you’re creative but don’t know finance, find a numbers person. Complementary strengths, not duplicate ones.

But the vetting is rigorous. Cody won’t partner with someone he wouldn’t hang out with. Someone he doesn’t respect. Someone he doesn’t see doing great work independently.

Most people partner with a friend and hope it works. Cody screens partners like he screens tenants.

The Systems Over Willpower Doctrine

This is the single most important decision Cody made early.

He didn’t rely on willpower to invest. He set up automatic systems where money was siphoned from his account before he even saw it.

On day one of earning, he set up automation: 10% to charity, 50% to savings, 20% to expenses, and 20% to spend freely.

Even when he was making $96,000 in year one and spending only $24,000, that system was locked in.

Most people say: “I’ll invest my bonus when it comes.” Or “I’ll start saving once I make more money.” They wait for perfect conditions.

Cody just automated it. Even if it was $10/month when he was broke, the system was running. By the time his income exploded, the system was already compounding.

The compound interest effect: $500/month invested at 8% annual return over 40 years (age 25 to 65) turns into $1.4 million. The discipline started at 19, so by 25, he had already built a $500,000 portfolio.

How to Balance Freedom (Travel, Experiences) With Financial Independence

This is where the FIRE movement gets it wrong.

They position financial independence as deprivation until you’re 65. Cody’s counter-argument: calculate what your dream life actually costs, then make that your target.

For him and his wife Lauren, the dream life is travel. So they travel. But they do it smartly: living in Australia for 6 months for $9,000 total. Travel hacking flights with points. Using points for hotels.

They still spend on what they value (travel and going out to eat), they just don’t spend on what they don’t value (cars, big houses, status symbols).

The framework: Write down what you actually value. Then check if your spending aligns. If you say you value family but work 60-hour weeks with no time for family, something’s wrong.

Cody and Lauren did this exercise. Their bank account shows: travel and eating out. So that’s exactly what they spend on.

The Book: A Menu, Not a Prescription

“Retire by 30” isn’t Cody saying “do what I did.” It’s Cody saying “here’s what worked for me, here are 10+ other case studies of people who retired before 30 different ways, choose your own path.”

Some people hit FI through real estate (like Dustin). Some through digital products (like Cody). Some through business ownership. Some through stock market investing.

The book is a choose-your-own-adventure guide to financial independence.

The key insight: There’s no single path. Find the path you’ll actually stick with—the one you get lost in and don’t notice 4 hours have passed.

The Real Setback: Dabbling in Too Many Things

If Cody has one regret, it’s trying 30+ side hustles simultaneously.

He thought: “The average millionaire has 7 income streams, so I should have 20.” But instead of accelerating wealth, it scattered his focus.

He’d pick up Uber Eats on a bicycle one week. Buff boats the next week. Freelance video editing the week after.

The problem: none of them got enough focus to scale. He was making small money from 20 things instead of big money from 2-3 things.

The lesson: Try things. Test. But once you find what works, hammer it. Build one income stream to serious size before adding the next.

This directly contradicts the idea that you should have multiple streams from day one. False. You build multiple streams over time, by focusing on one until it’s solid, then adding another.

The Dangerous Money Mistake Dustin Made (That You Should Avoid)

Dustin shared his own setback: he took his eye off the ball.

After years of grinding, building real estate wealth, his income was good. He relaxed. Took his family to Hawaii. Spent more freely. Got comfortable.

Then two months hit simultaneously with multiple evictions and property rehabbing. Suddenly no income was coming in, and he was spending instead of investing.

It set him back six months.

The warning: Once you start winning financially, don’t assume you’ve won forever. The discipline that got you there is the discipline that keeps you there. Drift from that discipline for even a few months and you lose momentum.

The System That Ingrained Wealth Into His Kids

Dustin’s 5 children all understand money in a way most adults don’t.

From birth, every penny they receive (birthdays, grandparents, Christmas) gets divided:

• 10% to giving/charity
• 50% to long-term savings (untouchable)
• 20% to household expenses (they pay for a portion of electricity, etc.)
• 20% to spend freely

By 16, his daughter bought her first rental property from her own savings. His son, at 15, has $9,000 saved and is buying his first property.

An 80% savings rate is ingrained in their DNA before they’re teenagers.

The reality: Most kids graduate college with $30,000 in debt and no savings. Dustin’s kids graduate with investment portfolios and real estate.

The Bottom Line: This Works at Any Age

The title is “Retire by 30,” but Cody’s clear: this works if you’re 50, 16, or anywhere in between.

His book shows case studies of people retiring in 3 years through real estate, 2 years through business, 7 years through corporate salary optimization.

The framework is the same regardless of age: create a gap between income and expenses. Invest that gap into scalable assets. Let compound interest do the work.

Cody hit financial independence at 25. Some of his friends beat him to it. Others will take longer.

The point: most people never try because they think 30 is impossible. Once they see it’s possible—once they see Cody did it, or read a case study in his book—they realize maybe they can too.

That’s the real gift of “Retire by 30.” It’s not the blueprint. It’s the proof that the blueprint is possible.

Go read the book. Pick your own path. Then execute with discipline.

The rest is just compound interest doing what it does best.
