How to Use Debt Strategically: Asset-Backed Loans, Business Financing, Mortgages and Credit Cards

Debt is often treated as inherently bad, but the more useful question is what the borrowed money is being used to accomplish. Debt used to fund consumption can become a long-term burden, while carefully structured debt can help preserve capital, acquire productive assets, grow a business, or maintain liquidity.

The difference comes down to leverage, risk, interest costs, cash flow, and the value of the asset supporting the borrowing. Several strategies illustrate how wealthy investors and business owners approach debt—and where ordinary borrowers can get into serious trouble.

Borrowing Against Assets Instead of Selling Them

One of the most powerful forms of leverage is borrowing against an asset that you already own.

A prominent example came from Elon Musk’s acquisition of Twitter, now X. Rather than selling all of his Tesla shares to fund the transaction, Tesla stock was pledged as collateral and a margin loan was used as part of the financing. The advantage of this structure is that the owner can retain the underlying shares, including their potential future appreciation and voting rights, while accessing liquidity.

The same principle can apply on a much smaller scale.

Suppose someone owns $100,000 in stocks and needs $20,000 to purchase another investment, fund a business, or make another major financial move. There are two basic choices.

Option 1: Sell the Investment

Selling $20,000 of the portfolio leaves $80,000 invested. If that remaining portfolio earns an annualized 10% return over five years, it grows to approximately $128,000, before considering the capital-gains tax associated with selling.

Option 2: Borrow Against the Portfolio

Instead of selling, the investor could potentially use a securities-backed line of credit (SBLOC) to borrow $20,000 while retaining the entire $100,000 portfolio.

At a hypothetical 6% interest rate, the loan costs $1,200 per year. Meanwhile, if the original $100,000 portfolio compounds at 10% annually, it reaches approximately $161,000 after five years. After accounting for $6,000 of interest over that period and assuming the borrowed money itself produces no return, approximately $135,000 remains after repaying the loan.

The comparison demonstrates the central principle: if an asset grows faster than the cost of borrowing against it, leverage can potentially increase wealth while allowing the underlying asset to remain invested.

The strategy becomes more attractive when the borrowed capital itself generates additional returns. However, that also increases the risk.

The Major Risk: Margin Calls

Asset-backed borrowing is not free money.

When securities are used as collateral, the lender monitors the relationship between the loan and the value of the collateral. If the underlying assets fall far enough, the borrower can receive a margin call.

At that point, additional collateral or repayment may be required. If the borrower cannot provide it, the lender can sell securities to recover its money—potentially when prices are already depressed.

That creates a dangerous combination: falling assets and forced selling.

Borrowing too aggressively can therefore turn a strategy designed to preserve wealth into a mechanism for destroying it. A high loan-to-value ratio provides little room for an asset to decline before the borrower faces pressure.

One conservative approach discussed for stocks is keeping borrowing around 20%–30% of the asset value, with even lower leverage—around 10%—for highly volatile assets such as cryptocurrency.

The exact appropriate level depends on the asset, interest rate, cash flow, and borrower’s risk tolerance. The key principle is maintaining enough room to survive a major decline without being forced to sell.

The “Borrow, Buy, Die” Concept

A related wealth strategy involves purchasing appreciating assets, borrowing against them, and continuing to hold them rather than selling.

The logic is that selling an appreciated asset can create a taxable event, while borrowing against it provides liquidity without an immediate sale.

For example, someone could acquire a rental property or business, borrow against its value, and use additional financing as assets accumulate. Interest payments and any required collateral support remain critical to keeping the strategy viable.

This approach is sometimes summarized as “borrow, buy, die.” The underlying idea is that assets are retained while borrowing provides access to capital, with the eventual estate handling outstanding debt.

This is an advanced strategy, not a shortcut around risk or taxes. Loan terms, tax rules, asset values, and cash flow all matter, and professional financial and tax advice is essential before attempting it.

Business Debt Can Create Much Greater Leverage

Business financing introduces another powerful form of leverage because a business can generate cash flow that helps service the debt.

Consider a hypothetical comparison involving $200,000.

If the money is invested in the stock market at an 8% return for eight years, the example produces roughly $370,000 in total value, or about $170,000 in gains.

The alternative is using the $200,000 as a 10% down payment on a $2 million business, financing the remaining amount with an SBA loan. Assuming 5% annual business growth, the example projects approximately $5.1 million after eight years.

The enormous difference comes from leverage: the investor controls a much larger productive asset using a relatively small amount of initial capital.

But leverage magnifies losses as well as gains. SBA loans can also involve a personal guarantee, meaning the borrower may have personal assets at risk if the business fails and the loan cannot be repaid.

That makes business acquisition dependent on serious due diligence.

Why Due Diligence Matters When Buying a Business

A business can look attractive because of its revenue while producing very little actual cash flow.

Consider a hypothetical luxury boat-rental business listed for $150,000, including the boat. It generates approximately $20,000 in annual revenue and only $10,000 in cash flow. Because the business operates in Lake of the Ozarks, seasonality also limits its ability to operate throughout the entire year.

The transaction would make little sense unless the underlying boat or other assets justified the purchase price.

The lesson is important: revenue is not profit, and a business acquisition should never be evaluated from the asking price alone.

Buyers need to understand cash flow, operating expenses, seasonality, assets, financing costs, and the actual economics of the business before taking on debt.

Seller Financing Can Reduce the Upfront Cash Requirement

Another form of business financing is seller financing.

Instead of requiring the buyer to provide the entire purchase price at closing, the seller effectively finances part of the transaction. The buyer can make a down payment and then use the business’s future profits to repay the seller according to agreed terms.

This can potentially reduce the cash required at closing and bridge the difference between what a bank is willing to finance and what the seller wants to receive.

A lawn-care business provides a useful example.

The hypothetical business is priced at $349,000, generates approximately $325,000 in annual revenue, and produces around $144,000 in cash flow—a roughly 44% profit margin.

With a 10% SBA down payment, the buyer would contribute about $35,000. A 10-year SBA loan would require approximately $51,000 in annual debt service, leaving about $93,000 in annual cash flow after debt payments.

That represents a 265% cash-on-cash return on the $35,000 down payment.

A seller-financed structure could work differently. One proposed arrangement involves paying the seller 40% of profits until $375,000 has been repaid, with the repayment occurring over approximately seven years. Under the example’s assumptions, this structure would leave the buyer with an additional $135,000 over a 10-year period compared with the SBA structure.

The exact numbers depend entirely on the negotiated terms and business performance, but the principle is broadly useful: financing terms can matter almost as much as the purchase price.

Business Growth Can Increase the Value of the Asset

A business itself is an asset whose value can rise or fall.

In the example presented, increasing a business’s value from $100,000 to $200,000 could potentially create a much larger increase in enterprise value because businesses are often valued using multiples of their financial performance.

Depending on the valuation multiple, an improvement of $100,000 in business value can therefore translate into several times that amount in enterprise value.

This is why improving both revenue and profitability can be powerful. The goal is not simply to make more money this year; stronger financial performance can also increase the value of the underlying business.

Mortgage Debt: An Asset or an Expensive Lifestyle?

A home is often described automatically as an investment, but buying a house can serve different purposes.

A mortgage does create a form of forced saving because part of every payment goes toward principal. That money becomes equity in the property rather than remaining available for everyday spending.

However, homeownership comes with costs beyond principal and interest:

• Closing costs
• Property taxes
• Insurance
• Repairs and maintenance
• HOA fees where applicable
• Mortgage interest

Average home appreciation since 2001 was cited at approximately 4.5% annually, while a 30-year mortgage could carry an interest rate around 6% in the example.

That means appreciation alone does not necessarily overcome the cost of borrowing.

Paying Down the Mortgage Versus Investing

Consider a $400,000 mortgage at 5% for 30 years. If the borrower pays an additional $800 per month, the mortgage could be paid off in roughly 17 years.

Alternatively, investing that $800 monthly at a hypothetical 7% return for those same 17 years could produce approximately $300,000. The example estimates the mortgage savings at roughly $245,000, creating a difference of around $60,000.

Over the full 30-year period, investing the same $800 monthly could result in approximately $975,000.

The comparison is not a guarantee that investing will outperform mortgage repayment. It illustrates the opportunity cost of directing every available dollar toward a relatively low-interest debt.

There is also a liquidity difference. Money used to pay down a house becomes tied up in the property. Money held in an investment account may be more accessible when a business experiences a difficult period, a vehicle requires repair, or another unexpected expense arises.

A useful framework is therefore to ask three questions:

1. What is the total cost of owning the property?
2. How much could the property reasonably appreciate?
3. What else could the capital be doing?

Renting can sometimes be financially sensible if the renter invests the difference consistently. But the strategy only works if the difference is actually invested rather than spent.

The Augusta Rule for Business Owners

Business owners may also encounter the Augusta Rule, which can allow a homeowner to rent their home to their business for up to 14 days per year under specific conditions.

For example, a business could use the home for a legitimate meeting or retreat and pay rent for the use.

Because tax treatment depends on detailed requirements, documentation, and individual circumstances, this is an area that should be reviewed with a CPA or qualified tax adviser rather than implemented casually.

Credit Cards: Useful for Float, Dangerous for Debt

Credit cards can provide short-term financing known as float.

A purchase made on June 1, for example, might not need to be paid until July 1. For a business, that gap can provide useful working capital: inventory can be purchased, sales can occur, and the card can be repaid afterward.

Rewards can add another benefit. The Capital One Spark Cash Plus, for example, was cited as offering unlimited 2% cash back on purchases.

Other cards can provide promotional financing or rewards. The Ink Business Cash Card was cited with an example of 0% interest for 12 months and 5% cash back on the first $25,000 spent in qualifying categories. The American Express Platinum card was highlighted for travel-related benefits such as lounge access and hotel credits, although it carries a substantial annual fee.

For businesses that need tighter control over employee spending, Ramp was cited as an example of a platform that can provide virtual cards, spending limits, and department-level expense tracking.

The fundamental rule is simple: credit cards should be paid in full every month.

Carrying a balance changes the economics completely. With average credit-card interest around 22% in the example, a $10,000 balance could generate more than $2,000 in annual interest, overwhelming a relatively small amount of cash-back rewards.

If credit-card debt already exists, optimizing rewards should take a back seat to eliminating the balance.

Two common repayment approaches are:

• Snowball: Pay off the smallest balance first to create psychological momentum.
• Avalanche: Prioritize the highest-interest balance first, which is mathematically more efficient.

The Core Rule for Using Debt

The most important distinction is not between debt and no debt. It is between productive leverage and destructive leverage.

Debt used to consume can create a cycle in which income is repeatedly used to service previous purchases. Debt used to acquire productive assets, preserve liquidity, or expand a profitable business can potentially create greater financial flexibility.

A useful principle is: never risk what you have and need for what you do not have and do not need.

The objective of smart borrowing is not to appear wealthier. It is to use capital in a way that increases financial resilience and opportunity without making the borrower dangerously dependent on rising asset prices or constant income.

Wealth is therefore less about working endlessly to service debt and more about building assets and businesses that can eventually operate without requiring every hour of the owner’s time. The strongest financing strategy is ultimately one that creates more control, not less.
