Buy, Borrow, Die: The Wealth Strategy Hiding in Plain Sight

If you have never heard the phrase “buy, borrow, die,” you are not behind. Most people have not. It is not a secret club handshake or a scam. It is a nickname for three ordinary rules in the U.S. tax code that, used together, let someone spend from growing wealth without selling assets and without paying capital gains tax along the way.

The idea sounds almost rude in its simplicity: buy things that go up in value, borrow against them when you need cash, and hold those assets until death. At that point, the tax code often wipes out a lifetime of unrealized gains for the next generation.

This is not magic, and it is not available in the same way to everyone. It also is not a free lunch. Below is how it works, why it exists, who it actually helps, and where it can blow up.

The three-sentence version

Buy assets that you expect to appreciate — stocks, a business, real estate, and similar holdings — and do not sell them.

Borrow against those assets when you need money, because a loan is not treated as taxable income.

Die holding the assets, so heirs generally receive a “step-up in basis,” which can erase the capital gains that built up during your lifetime.

That last step is the part most people miss. Borrowing only defers tax. Death, under current law, can eliminate it.

Why ordinary people pay tax when the wealthy often do not

Most households live on wages. Wages are taxed when they are earned. If you later sell an investment that has gone up, you pay tax on the profit. That profit is a capital gain.

The tax system generally waits for a “realization event” before it taxes investment growth. Selling is a realization event. Watching a stock climb from $20 to $200 is not. Those paper profits are called unrealized gains, and they are not taxed until you sell.

That single fact is the foundation of the strategy. If you never sell, you never trigger the capital gains bill. The problem, of course, is that you still need cash to live, buy a house, start a company, or pay bills. The wealthy answer is not “sell.” It is “borrow.”

Step 1: Buy assets that can grow for decades

The first move is not exotic. You acquire assets that can compound for a long time and that you can hold in a taxable account.

Common examples include:

• A diversified stock portfolio or index funds

• Founder’s shares in a company

• Investment real estate

• A privately held business

• In some cases, other appreciating assets such as art

The key is holding. Every sale restarts the tax clock. Every year you do not sell, the asset can keep compounding on the full amount, including the portion that would have gone to the IRS if you had cashed out.

This is why the strategy is weakest with assets that throw off a lot of ordinary taxable income and strongest with assets whose value mostly sits in unrealized growth.

One more limit matters immediately: this playbook is about taxable accounts. Traditional IRAs and 401(k)s do not get a step-up in basis. Heirs generally pay ordinary income tax on those inherited retirement accounts. The strategy lives in brokerage accounts, real estate, and similar holdings.

Step 2: Borrow instead of sell

Suppose you bought $250,000 of stock years ago. It is now worth $1.2 million. You want $200,000 for a home down payment.

If you sell $200,000 of stock, you realize a large gain and owe capital gains tax. After federal tax — and possibly the 3.8% net investment income tax plus state tax — you keep less than you sold. You also shrink the portfolio that was compounding for you.

If instead you open a securities-backed line of credit, sometimes called a pledged asset line or portfolio line of credit, you pledge the investments as collateral and borrow the $200,000. The IRS does not treat loan proceeds as income. You receive cash. You also receive a debt. No sale, no capital gains tax.

The portfolio stays invested. If it keeps growing faster than the interest on the loan, the math can look attractive. You spent money. The assets kept working. The tax bill never arrived.

Real estate owners have used a cousin of this idea for a long time: a cash-out refinance or HELOC. You do not sell the house. You borrow against equity. The cash is still a loan, not a sale.

That is the “borrow” in buy, borrow, die.

Step 3: Die — and the basis resets

This is the unsentimental part of the name, and it is also the part that turns deferral into something closer to cancellation.

Under current U.S. law, when you die, many inherited capital assets receive a new cost basis equal to fair market value on the date of death. That rule is called a step-up in basis. It lives in the tax code as Section 1014.

Imagine you bought stock for $1 million. At your death it is worth $11 million. Your heir’s basis becomes $11 million. If the heir sells immediately at $11 million, there is no capital gain to tax. The $10 million of growth from your lifetime is gone from the income-tax system.

Outstanding loans do not vanish into the air. They are debts of the estate. Heirs can sell some of the inherited assets — now at the new, higher basis — and use the proceeds to repay the lender with little or no capital gains tax on that sale.

That is why the strategy is described as a loop: grow, tap, transfer, reset.

A kitchen-table numbers example

Meet Jordan. This is a simplified illustration, not a forecast.

Jordan invests $300,000 in a taxable brokerage account. Twenty years later it is worth $1 million. Jordan needs $200,000.

Path A: Sell.Jordan sells $200,000 of stock. Assume a large embedded gain and a combined federal tax rate around 23.8% on the gain, before any state tax. After tax, Jordan might net well under $200,000 of spending money and now owns a smaller portfolio. The sold shares stop compounding.

Path B: Borrow.Jordan borrows $200,000 against the $1 million portfolio. No sale. No capital gains tax. The full $1 million remains invested. Interest is a real cost, paid from cash flow, dividends, or more borrowing.

If the portfolio later grows and Jordan dies still holding it, heirs can inherit the assets at the new market value. They can sell enough to repay the loan and keep the rest, often without paying tax on Jordan’s lifetime gain.

The difference is not that borrowing is “free.” Interest is a cost. The difference is that selling creates an immediate tax and permanently removes assets from compounding, while borrowing delays — and death may erase — that tax.

Real-life examples, from the famous to the familiar

Elon Musk and pledged stock

Public company filings have shown Elon Musk pledging large blocks of Tesla shares as collateral for personal loans. The logic is straightforward: selling shares can trigger a huge capital gains tax and can also reduce control. Borrowing against shares raises cash without a sale. Reporting over the years has described those pledged shares as an ongoing source of liquidity.

That is buy, borrow, die at billionaire scale. The “buy” was equity in a company that exploded in value. The “borrow” was loans secured by that equity. The “die” piece is the long-term tax design of the estate, not a prediction about any one person.

Larry Ellison and Oracle shares

Oracle’s founder, Larry Ellison, has long been cited as a textbook case. Company disclosures have shown billions of dollars of Oracle stock pledged as collateral for a personal credit line. Those loans have been linked in reporting to a very expensive lifestyle — homes, a yacht, an island — funded without a matching sale of stock.

Again, the mechanism is ordinary: appreciated shares stay in place, cash comes from lenders, and the tax on the gain is not triggered by the borrowing.

A small-business owner who never sells the company

This version is less flashy and more common among successful private owners.

A woman starts a manufacturing firm in her 30s. She takes a modest salary. The company becomes worth $8 million. If she sold it, she would face a large capital gains tax and lose the asset that produces her wealth. Instead she holds the business, borrows against company or personal assets when she needs liquidity, and leaves the company to her children. At death, the heirs’ basis in the business can reset to current value. They can sell later, or sell enough to clean up debts, without inheriting her embedded gain in the same way.

A long-term homeowner or rental investor

A couple bought a rental duplex for $280,000 in the early 2000s. It is now worth $750,000. Selling would mean capital gains tax, possible depreciation recapture, and the loss of a cash-flowing asset. A cash-out refinance pulls tax-free loan proceeds against the equity. Tenants still help carry the debt. If the property is held until death, heirs can receive a stepped-up basis in the real estate under current rules.

That is the same skeleton as the billionaire version, built from a duplex instead of a rocket company.

The tax code pieces that make it legal

Three rules do almost all the work:

1. Unrealized gains are generally not taxed until you sell.

2. Borrowed money is not income.

3. Inherited assets often get a stepped-up basis at death.

None of those rules was written as a slogan. Together they create an asymmetry. A surgeon who earns $400,000 in wages pays tax as the money arrives. An investor sitting on $400,000 of paper gains can leave that money untouched, borrow against it, and, if the rules stay as they are, pass the asset on with the gain cleaned off.

That is why critics call step-up in basis a loophole and why supporters call it a way to avoid taxing the same economic value twice — once as income and again through the estate tax. Both descriptions are arguments about policy. The mechanics are not in dispute.

Who this actually works for

The internet often treats this as a billionaire-only trick. The plumbing is available more broadly than that. Many large brokerages offer securities-backed lines of credit to clients with sizable taxable portfolios. Landlords refinance. Business owners pledge assets.

But the strategy is not a mass-market product in practice, and researchers have pushed back on the idea that it is the main way the rich avoid tax. Analyses of household data have found that annual new borrowing by the top 1% is relatively small compared with their unrealized gains. A lot of wealthy households simply save and hold. One research summary put it as “buy, save, die” more than “buy, borrow, die.”

It works best when several conditions line up:

• You already own appreciated assets in a taxable account

• Those assets are acceptable collateral

• You can service the interest without stress

• You are willing to stay invested through ugly markets

• Your estate plan accounts for debts and, if the estate is large enough, estate tax

It works poorly if your wealth is mostly in a 401(k), if you need to sell to rebalance or survive a downturn, or if a single stock is both your nest egg and your collateral.

The risks people skip in the viral version

This strategy uses leverage. Leverage is a multiplier. It multiplies mistakes too.

Margin calls and forced sales. If the collateral drops enough, the lender can demand more cash or sell the assets. A forced sale in a crash can trigger the exact capital gains tax you were trying to avoid, at the worst possible price. Concentrated stock makes this danger sharper.

Interest is not theoretical. If the loan costs 7% and the portfolio returns 4% for a stretch, you are slowly eating the asset. Rising rates can turn a clever tax deferral into an expensive habit.

Estate tax still exists. Step-up can erase income tax on unrealized gains. It does not automatically erase estate tax. Very large estates can still face a steep estate tax. A loan reduces the net estate, which can interact with estate tax planning, but “no capital gains” is not the same as “no tax of any kind.”

The rules can change. Step-up in basis and the tax treatment of borrowing against appreciated assets have been political targets for years. As of now the core rules remain in force, but a strategy that depends on Congress leaving a provision alone is not a law of physics.

Behavior risk. The strategy tempts people to stay too concentrated, borrow too much, and confuse “I have a credit line” with “I have income.” Those are different things.

What this means if you are not already rich

You do not need a yacht for the underlying lessons to matter.

First, unrealized gains are a real form of wealth, but they are fragile until you sell or die holding them. Second, selling is a tax event; borrowing is a financing event. Third, location matters: the same index fund in a brokerage account and in an IRA follows different tax rules at death.

A more realistic version for many households is milder than the full slogan. Hold appreciating assets long enough to benefit from compounding. Be slow to sell low-basis positions if you have another way to raise cash. Use cheap, conservative borrowing only when the numbers and the risk truly work. Build an estate plan so heirs are not surprised by debts or tax surprises.

The full billionaire loop — live for decades on loans against a concentrated fortune, then let death reset the basis — is a high-wire act. The idea behind it is more ordinary: the tax system taxes realized income more reliably than paper wealth.

The honest bottom line

Buy, borrow, die is a nickname, not a product you order from a bank. It describes how three existing tax rules can be stacked: do not realize gains, raise cash through debt, and use the step-up at death to clear the embedded gain for heirs.

It can preserve a lot of wealth. It can also magnify a market collapse, rack up interest, and leave an estate tangled in loans. It is legal under current law. It is not a substitute for earning money, saving money, or holding assets that actually grow.

If the phrase sounded like a riddle when you started this article, it should now sound like a sequence. Buy things that compound. Think hard before you sell them. Understand that a loan can unlock cash without unlocking a tax bill. And remember that the last word in the strategy is not a punchline. It is the part of the tax code that makes the first two words so powerful.
