“Buy, Borrow, Die” is one of those phrases that makes a complicated financial idea sound almost effortless. Buy assets. Borrow against them. Hold them until death. That is the slogan. The actual planning is much more complicated.
The concept can involve capital gains, borrowing costs, estate rules, asset values, liquidity, and tax law. It can also create real risk if someone borrows too aggressively or assumes the rules will always work in their favor.
Step 1
Buy Assets That May Appreciate.
The first part is simply owning assets that may increase in value over time. That can include real estate, publicly traded securities, a privately held business, or other investments. Nothing guarantees appreciation.
If an asset rises in value and you sell it, the sale may create a taxable gain depending on basis, holding period, use of the property, and other facts. Selling can create liquidity, but it may also create tax consequences.
Illustrative example only
- Property purchase price
- $1,000,000
- Illustrative adjusted basis
- $1,100,000
- Current value
- $2,000,000
- Unrealized appreciation
- $900,000
If the owner sells, some portion of the gain may be taxable depending on the property, basis, depreciation, holding period, exclusions, and other facts. Unrealized appreciation is not the same as taxable gain.
Appreciation is not cash until you sell or borrow against the asset.
Step 2
Borrowing Can Create Liquidity Without Selling the Asset.
A loan can provide cash while the borrower continues to own the underlying asset. Under current tax principles, genuine loan proceeds generally are not included in gross income because the borrower has an obligation to repay the lender. If debt is later canceled or forgiven, canceled-debt income may arise depending on the circumstances.
Borrowing can take many forms depending on the asset: a mortgage, HELOC, cash-out refinance, business loan, or other collateralized credit. I work in mortgage and real-estate financing; I do not arrange securities-backed credit.
Borrowing may allow an owner to access liquidity without triggering a sale. That does not make the borrowing free.
The Part the Slogan Leaves Out
Borrowing Only Works If the Debt Still Makes Sense.
Interest, origination costs, variable rates, maturity, monthly payment, collateral risk, declining asset values, debt-service requirements, and refinancing risk all matter. For property-backed borrowing, interest cost, loan term, prepayment terms, and how much equity remains in the property all matter. Whether interest is deductible depends on how borrowed funds are used and other tax rules. Do not assume borrowing costs are always deductible.
If the asset appreciates more slowly than expected, or borrowing costs rise, the math can change quickly. Leverage does not automatically improve returns.
Option A
Sell part of the asset and create cash.
Option B
Keep the asset and borrow against it.
Compare what taxes may result from selling, what the loan costs, how long the debt may remain outstanding, what the payment is, what happens if the asset falls in value, how much liquidity remains, what happens if rates change, and what the exit plan is. There is no universal winner. The answer depends on the numbers.
Step 3
Inherited Basis Rules Are Why the Final Part of the Phrase Gets So Much Attention.
Current IRS guidance generally provides that property acquired from a decedent receives a basis tied to fair market value at the date of death or under another permitted valuation method, subject to exceptions. If appreciated property receives a basis adjustment at death, the built-in gain that accumulated during the decedent's lifetime may be reduced or eliminated for future capital-gain calculations, depending on the circumstances.
Illustrative only
- Original adjusted basis
- $1,000,000
- Value at death
- $2,500,000
- Potential inherited basis
- Approximately $2,500,000 under the general FMV-at-death rule
If the heir later sells at roughly that value, the capital gain may be very different from what the original owner would have recognized if they had sold before death. This does not mean the transfer is automatically tax-free. Estate tax, state tax, ownership structure, prior gifts, valuation rules, and other issues may apply.
A Separate Issue
Basis and Estate Tax Are Not the Same Thing.
The basis rules used to measure capital gain are separate from the federal estate-tax system. For decedents dying in 2026, IRS filing guidance lists a federal estate-tax filing threshold of $15,000,000 for the gross estate (before unified credit and other rules). That threshold can change with law. Married couples may have additional planning options, including portability when an estate tax return is filed, but those details belong with an estate attorney and tax professional.
State estate or inheritance taxes may also apply depending on where the person lives and what they own. Being below the federal filing threshold does not mean there is nothing to plan for.
The Tradeoffs
The Strategy Can Fail If the Borrowing Gets Ahead of the Assets.
Assets can decline. Lenders can reduce available credit. Rates can rise. Income can change. Debt still has to be serviced. Refinancing may not always be available. Heirs may inherit debt alongside assets. Estate settlement may require liquidity. Laws may change. The phrase makes the strategy sound passive. In reality, it requires ongoing risk management.
There are plenty of situations where borrowing more is the wrong answer: unstable income, already-high leverage, poor liquidity, a short holding period, expensive borrowing, an uncertain repayment plan, heavy asset concentration, a foreseeable sale, or high carrying costs. Sometimes selling an asset, paying the tax, reducing debt, or doing nothing is the better decision.
Where Real Estate Fits
Real Estate Makes the Borrowing Piece Easier to See.
A homeowner or investor with substantial equity may consider a HELOC, home equity loan, cash-out refinance, or investment-property refinance instead of selling to create liquidity. The choice depends on the existing first mortgage, current rate, available equity, cash needed, intended use, monthly payment, borrowing cost, hold period, tax implications of a sale, and future property plans.
The Loan Already in Place
Sometimes the Most Valuable Debt Is the Debt You Already Have.
If a property owner has a low-rate first mortgage, replacing the entire loan to access equity may create a very different cost than using a second-position loan. For another borrower, restructuring the entire mortgage may make more sense. The financing decision should be compared as a whole.
Cash Matters Too
Net Worth and Liquidity Are Not the Same Thing.
Someone can own millions of dollars in appreciated assets and still have relatively little cash available. Borrowing may create liquidity, but it also creates debt. The question is not simply how much equity exists. It is whether accessing that equity improves the overall position after interest, payments, and risk are considered.

Who Should Be in the Conversation
This Is Usually a Team Decision.
A CPA or tax professional may address tax consequences. An estate-planning attorney may address estate structure and legal documents. A financial adviser may address portfolio implications. A mortgage professional may address real-estate financing. Not every person needs every adviser on every decision.
My Role
I Focus on Whether the Financing Actually Makes Sense.
If you are considering using real estate equity instead of selling an asset, I want to understand why. How much cash do you need? What debt is already in place? What does the new payment look like? What does the loan cost? How long do you expect to keep it? What happens if the plan changes?
I can help you evaluate the mortgage side of that decision. I will not tell you whether a tax or estate strategy is right for you. That belongs with the professionals who advise you in those areas. If borrowing is part of the plan, I want the numbers to make sense.
