Preserving Wealth · Avoiding Pitfalls

The biggest money mistakes people make

If something I’ve learned over the years can help someone avoid a mistake or build a stronger future, then sharing that knowledge is worthwhile.

One of the most common questions I receive through Ask Mark is about money. People want to know how to build financial stability, invest wisely, and avoid the traps that keep so many people stuck.

The truth is that most financial problems don’t come from complicated investment mistakes. They come from a handful of very common habits and misunderstandings.

Trying To Look Rich Instead Of Becoming Stable

One of the most damaging financial habits is spending money to create the appearance of success. People buy cars they cannot afford, live in houses that stretch their finances, and carry credit card balances just to maintain a lifestyle that impresses other people. Real financial stability comes from living below your means and making decisions that strengthen your future rather than impress people today.

Waiting Too Long To Start Investing

Time is one of the most powerful forces in building wealth. Even small investments made consistently over time can grow into significant resources later in life. Many people delay investing because they think they need large amounts of money to begin. In reality, starting early with small amounts is far more powerful than starting late with larger amounts.

Not Understanding Debt

Debt can be a tool, but it can also become a trap. Understanding the difference between productive debt and destructive debt is critical. High-interest consumer debt, especially credit cards, can quietly drain a person’s financial future. Debt that helps you build assets or generate income can sometimes be useful. Debt that simply funds consumption often becomes a burden.

Depending Too Much On One Income Source

Many people rely entirely on a single paycheck. Building additional sources of income — even small ones — can create resilience. This might include investments, rental property, side businesses, or other forms of income generation. Financial independence often begins when people stop relying on a single source of money.

Ignoring Long-Term Planning

Without a plan, it becomes easy to drift financially rather than move intentionally toward stability. Many work hard and earn income, but they don’t have a long-term plan for retirement, investments, asset building, or generational wealth.

Believing That Money Solves Every Problem

Money is important, but it is not the only thing that matters. Many people sacrifice relationships, health, and personal values in pursuit of financial success. Money should support your life — not replace it.

Lessons From the Road

The longer version

Specific situations that cost people real money — rental property, debt, MLMs, precious metals, insurance — and what I’d do instead.

Income Properties To Build Wealth

I didn’t grow up with a roadmap for building wealth, so I’m writing this one down — mostly for my kids and grandkids, but if it helps your family too, that’s a bonus. The first rule is simple: stop piling up debt. My kids figured that out and taught their kids the same thing, and watching that happen is one of the best things I’ve seen in my life. Somewhere along the way we stopped thinking about money as a pile you’re always chipping away at, and started thinking about it as a river — you dip in what you need, and more keeps flowing behind it. That’s the difference between being scared of your bank account and actually having security.

If you own a big house with a big mortgage, your next move shouldn’t be a bigger house — it should be a small one, paid off, that you could move your whole family into if everything else fell apart. My wife and I have said it to each other more times than I can count: if a deal goes sideways or a partner burns us, we can always move into the rental. That’s not pessimism, that’s just knowing your floor. I want to see every American family own a home free and clear, even if it’s a modest one, because that’s the difference between wealth that can disappear overnight and wealth that can’t.

The Insane Problem With MLMs

I’ve had people try to recruit me into more than one MLM over the years, and I actually joined a couple just to study how they work before I said no thanks. Here’s what I found: it’s never really about the product. It’s about how many people you can get to join underneath you, and the math only works for the person at the very top. Ninety-nine percent of people who join one of these lose money or make next to nothing once you count what they spent to join. The saddest part isn’t the money — it’s watching someone burn through their real friendships trying to recruit the people they love, and then losing those friendships when it doesn’t work out.

The way you spot one of these before it costs you anything: they always come to you as a fellow struggler who found the answer, not as a business selling you something. Ask them straight out what they’re actually selling, and if the answer is “check your DMs” instead of a plain answer, that tells you everything. Real help is upfront about the cost. If I want to help you with something, you’ll know exactly what it costs and what you’re getting — no course to buy first, no forcing you to recruit two more people before it’s free. I don’t charge anything for what I do here, and if somebody’s telling you they’ll “retire your husband” or hand you a free car, do the math on what that car lease actually costs you before you sign anything.

Tenant Move-Out: The One Thing Most Landlords Miss

One of the money mistakes I see landlords make constantly is skipping documentation, and it always costs them later. Every time we move a tenant in, we walk the whole property on video together — them and us — and I ask them to point out anything that’s wrong before they move in. We look at every room, test the toilets, check the appliances, and I explain what’s their responsibility to maintain, like changing the air filter every few months. That video, plus photos of everything including the flaws, becomes the record both sides agreed to. It costs nothing and it protects everyone.

The same thing happens on the way out. We walk through again, on video, and talk through what we’re seeing — a stain here, a crack there — while the tenant is standing right next to us. When that stove turns out to still work fine and someone claims it never did, we’ve got proof. When the carpet comes back damaged and someone says it was already like that, we’ve got proof of that too. This isn’t about being suspicious of people — it’s about not leaving thousands of dollars of a decision up to two different memories of the same day. Document everything, every time.

How To Avoid Getting Scammed Buying Silver

If you’re going to buy physical silver, the first thing to learn is the spot price — that’s the real-time market value of the metal, and it moves every day. A reputable dealer will sell to you a little above spot and buy back from you a little below it. If someone at a pawn shop offers you 20% under spot, that’s not “gotta make a little too,” that’s them taking most of your money. Learn the number before you walk in anywhere, because a dealer that respects you will let you check it yourself.

The scams I keep seeing come from social media, and they’re easy to spot once you know what to look for. Somebody sells a coin made of titanium and calls it a “silver eagle replica,” or a fractional “silver” bar priced way above what the actual grams would be worth even at full silver value. A real one-ounce round from a name-brand dealer costs around a hundred dollars — if you see a “collector coin” that looks like an ounce of silver for twelve or thirteen dollars, it isn’t silver. And if the seller has comments turned off, that alone should tell you people have already caught them. Buy from a dealer with a track record, verify the weight and purity, and skip anything sold with pressure and no real answers.

Why “Be Your Own Banker” Life Insurance Isn’t For You

People sell “infinite banking” or “be your own banker” as a way to escape the ups and downs of the stock market using a whole life insurance policy. Here’s what actually happens: you overfund a policy, and then you borrow against your own cash value at 9–12% interest to pay for things, while the insurance company keeps using your money the whole time. The first year or two of premiums mostly go to pay the commission of the person who sold it to you. It’s marketed to people who are scared and hand-to-mouth, but it was really built for people who are already wealthy and need estate-planning tools — not for a family with $300,000 trying to protect their retirement.

Life insurance has one real job: replacing your income if someone depends on it and you’re gone. If you have young kids and a spouse who counts on your paycheck, a term policy makes sense. Once nobody depends on your income anymore, you don’t need it — and you definitely don’t need it as an investment. If you’d taken the money from a cheaper term policy and just put it in a plain S&P 500 index fund over the last 20 years, you’d have come out ahead of a whole life policy paying 4–5%. The market goes up and down, and past performance never guarantees the future — but don’t let fear about volatility talk you into a guarantee that mostly guarantees someone else’s commission.

The 1% Rule That Keeps Rental Property From Losing You Money

The mistake I see over and over with rental property is people paying too much for the house relative to what it can actually rent for. Our rule is simple: monthly rent needs to hit 1% of what you paid, or better. Buy a $50,000 house, it needs to rent for $500 a month. If you pay $300,000 for a house in a neighborhood where rent tops out around $1,700, the math will never work — and if you force it by charging above-market rent to make your payment, you’ll either sit empty or end up with the one tenant desperate enough to pay it, which is usually not the tenant you want. I rent my houses for less than the neighborhood average, and it’s not charity — it’s how I get the best tenants with the best credit, because good tenants have options and they take the good deal.

The other money mistake landlords make is skipping the work of actually screening tenants. We don’t just run an application and hope — we get on the phone with every applicant and talk it through: no evictions, no criminal background issues, income at three times the rent, and a credit score over 650. If someone’s short on one of those but strong everywhere else, we’ll work with them. If they’re weak on two, we tell them straight up so they don’t waste $35 or $40 on an application fee we already know won’t work out. That conversation takes time — sometimes an hour on the phone — but it’s the difference between a tenant who takes care of your property for years and one who costs you a full renovation.

Why I’m Telling Everyone To Hold Off On Buying A Car Right Now

The car market crash people are finally starting to talk about isn’t new to me — I saw this coming two years ago, and I’ve been telling anyone who’ll listen to wait three to six months before buying a car right now. Dealers are rolling out incentives that look great in the ads, but incentives are a symptom, not a gift. They’re a sign that inventory built up faster than demand, and a dealership offering you thousands off isn’t doing you a favor — it’s telling you the price still has further to fall.

This is why I keep pointing people back to timing instead of this month’s deal. Once you understand how these inventory and pricing cycles move, you stop reacting to whatever offer is in front of you and start watching for the moment the market actually favors the buyer. If you don’t need a car this week, give it a little more time. Let the dealers compete for you instead of the other way around.

Why I Ran My Business Completely Debt-Free For 25 Years

I started a computer recycling company in 1994 called Action Computers, and I ran it debt-free from day one. We never borrowed a dollar — not for inventory, not for the truck, not for the warehouse. Everything we had in the early days was used, including the office chairs, and when we finally bought a warehouse, we paid cash for it because we’d saved up the money first. I sold that company in 2019, twenty-five years after I started it, and by then it had outlasted RadioShack, CompUSA, Circuit City, and honestly hundreds of other tech retailers that went under along the way. The guys who bought it are still running it profitably today. That’s not luck — that’s what happens when debt never gets a vote in how you run things.

I bring this up because the exact same mistake is playing out in Las Vegas right now. Casinos sold off the buildings they used to own to landlords, took the cash to expand, and now they’re locked into rents so high they’re charging $45 for a ham sandwich and $25 a hand just to sit at a table — and they’re still hemorrhaging money because people have finally stopped showing up. They borrowed against an asset to grow fast, and now that asset owns them. You’re seeing the same thing with car dealers who spent the last few years marking trucks up $10,000 to $15,000 over sticker — the public’s answer was to simply stop buying.

This is why I tell people: if you’re carrying debt, the guy sleeping on the street with nothing is closer to wealthy than you are — he’s at zero, you’re in the negative. Charlie Munger used to say he wasn’t chasing money for a Ferrari, he wanted independence — not owing anybody anything. I still make an exception for a primary home and for rental property, but even there I don’t borrow against the asset itself — I buy in cash or I bring in partners. Ten friends who each put up ten thousand dollars can buy a rental outright with no mortgage at all. It’s not as flashy as leveraging up to buy ten houses with financing, but when the market turns — and it always turns — the cash buyer is still standing and the leveraged one isn’t.
