Interest-producing investments

Direct Business Lending

Lending your own money to an operating business under a note you negotiate, rather than through a fund or a public market.

Direct business lending means making a loan straight to a company — a local operator, a franchisee, a supplier — documented by a promissory note and usually secured by business assets and a personal guarantee. The lender sets the rate, the amortisation and the collateral, and takes the credit risk with no diversification and no manager in between. It is the private, one-loan-at-a-time version of what private credit funds do at scale.

Interest from lending Semi-passive

The labels above place this income type before you read a word. The first is the mechanism — how the money actually reaches you, whether by lending it out, owning a slice of something, renting an asset, licensing a right, selling an option or owning a business somebody else runs. The second says whether the income keeps arriving on its own once it is running, or whether it needs work from you to keep coming. Both are descriptions of how the thing is built, not verdicts on it.

Category caveat
Everything in this category pays interest, but the safety net behind that interest varies enormously. A bank deposit is insured by the FDIC up to the standard federal limit, a Treasury is an obligation of the US government, an agency debenture is the promise of a chartered company, and a private note is backed only by the borrower and whatever collateral secured it. The rate on offer is largely the market's price for that difference, and for how long you agree to wait.

How it works

The core document is a promissory note: principal, interest rate, payment schedule and maturity date, spelled out in terms the lender negotiates directly with the borrower. For anything beyond a handshake amount, the note usually sits inside a broader loan or credit agreement that adds covenants (financial ratios, reporting deadlines, restrictions on further borrowing) and default remedies.

Security, when there is any, comes from a separate security agreement pledging specific business assets — receivables, inventory, equipment — as collateral. That interest only protects the lender once it is perfected, which for most business assets means filing a UCC-1 financing statement in the borrower's state of organization. An unfiled or misfiled interest is, in practical terms, no security interest at all.

In small-business lending a personal guarantee from the owner is standard practice, because it reaches assets the owner holds outside the company — a house, personal savings — if the business itself cannot pay. If a bank already lends to the business, the new loan is typically subordinated to it, and a subordination or intercreditor agreement spells out payment priority and who is allowed to enforce first.

Repayment can follow straight amortization, an interest-only period ending in a balloon payment, or a revenue-based structure where the borrower remits a fixed percentage of monthly sales until a set repayment multiple is reached. State usury statutes cap the interest rate that can legally be charged, and several states require a commercial lending license; both rules vary by state, borrower type, and loan purpose.

What it pays

The headline number is a stated annual interest rate, sometimes paired with origination points collected at closing, which push the effective return above the coupon rate itself. Unlike a bond or a bank CD, there is no market setting the price — the rate is whatever the lender and borrower agree to, shaped heavily by what the borrower's other options would cost: a bank line, an SBA-guaranteed loan, or a merchant cash advance.

Collateral quality and lien position drive most of the pricing. A first lien on marketable, hard assets prices tighter than an unsecured or subordinated note, because recovery in a default is far more predictable. Revenue-share arrangements skip a stated rate entirely and instead quote a repayment multiple — the effective annualized return then depends entirely on how quickly the business's sales grow.

Warrants, profit participations, or success fees sometimes get layered onto a junior or higher-risk note as compensation for taking a weaker position; these pieces behave like equity, not interest, and carry equity's upside and its uncertainty. Because there is no secondary market and no mark-to-market, the realized return is binary in a practical sense — it is either the contractual payment stream in full, or whatever comes out of a workout or liquidation.

Costs and taxes

Closing a note properly costs real money: legal drafting of the note and security agreement, lien searches on the borrower and any guarantor, UCC filing fees, and — if real estate secures the loan — title work and recording fees. Servicing the loan afterward is either the lender's own unpaid time or a fee paid to a third-party servicer.

Interest received is ordinary income for federal tax purposes, and where required the borrower reports it to the lender and to the IRS on Form 1099-INT. A loan priced below market can trigger the imputed-interest rules, which require interest income to be reported at the applicable federal rate regardless of what was actually charged — a real trap for casual or below-market family and friend loans.

If the loan goes bad, the tax treatment of the loss depends on a threshold question: is lending the trade or business of the lender? A business bad debt is deductible against ordinary income, while a non-business bad debt is treated only as a short-term capital loss, which is far less favorable. Origination points are generally not recognized entirely at closing but spread as income over the life of the loan.

Liquidity and time commitment

A single, privately negotiated note has no secondary market. Selling one means finding a willing buyer and formally assigning both the note and its underlying security — a process few lenders have set up in advance. The capital is committed until the loan amortizes fully or the borrower refinances a balloon payment, which makes the borrower's own refinancing plan a real dependency of the investment.

The heavy work happens up front: reviewing financial statements and tax returns, checking bank statements, running background and lien searches, valuing collateral, and negotiating the note, security agreement, and any subordination terms. That underwriting is not optional diligence — it is the entire risk control, since there is no fund manager or rating agency doing it instead.

Once funded, ongoing effort shifts to monitoring: collecting the covenant reporting the loan agreement requires, watching for late or missed payments, and keeping UCC filings current by refiling continuation statements before they lapse. If the loan sours, the time commitment rises sharply — workout negotiations, collateral foreclosure, or litigation to enforce a personal guarantee all take months and legal fees.

How it goes wrong

The most common failure is simple: the business fails, and the pledged collateral turns out to be worth a fraction of the loan balance. Used equipment and specialized inventory routinely sell for very little at a distressed sale, and receivables pledged as security can be concentrated in one customer, disputed, or already pledged to a factor without the lender's knowledge.

Perfection failures compound the problem — a UCC filing made in the wrong jurisdiction, or a continuation statement that lapses unnoticed, lets a properly perfected creditor jump ahead in priority. A personal guarantee is only as strong as the guarantor's unencumbered personal assets, which are frequently already pledged elsewhere or held in a form that resists collection.

Bankruptcy changes the game entirely: an automatic stay halts collection efforts, and unsecured or subordinated lenders typically recover little once secured creditors are paid first. Charging interest above a state's usury cap, or lending without a required license, can render the interest unenforceable and in some states put the principal itself at risk.

A quieter but reliable failure mode is relational: lending to friends, family, or a business the lender also works with mixes personal loyalty with credit judgment, which routinely delays the hard conversations — demanding payment, enforcing a default — until recovery is no longer realistic.

What to remember

  • Direct business lending means negotiating and documenting a single loan yourself, taking full credit risk with no fund manager and no diversification.
  • Returns come from a negotiated interest rate plus any points, priced mainly by collateral quality and where your lien sits relative to a bank.
  • The capital is illiquid until the loan is repaid or refinanced — there is no secondary market for a single private note.
  • Security only matters if it is properly perfected with a UCC-1 filing, kept current, and backed by a guarantor with real unencumbered assets.
  • Tax treatment of both the interest and any eventual loss depends on structure — imputed-interest rules for below-market loans, and business versus non-business bad-debt rules for losses.
  • The largest risks are borrower failure with weak collateral recovery, subordination behind a bank, lapsed liens, and state usury or licensing violations.

Frequently asked

What paperwork does a direct business loan need?
At minimum a promissory note stating principal, rate, payment schedule and maturity. Secured loans add a security agreement describing the collateral and a UCC-1 financing statement filed with the borrower's state to perfect the lien. Small-business loans usually add a personal guarantee, and any loan behind a bank needs a subordination or intercreditor agreement.
What does perfecting a lien mean?
Signing a security agreement gives you rights against the borrower; perfecting gives you priority against other creditors. For most business collateral, perfection means filing a UCC-1 financing statement in the correct state. Filings lapse after five years unless a continuation statement is filed, and a lapsed filing can drop a first-priority lender behind everyone else.
Is there a legal limit on the interest I can charge?
Yes, and it varies by state. Usury statutes cap rates, often with different limits for consumer and commercial loans and exemptions for licensed lenders or loans above a certain size. Some states also require a lender licence for commercial lending. Exceeding the cap can render the interest unenforceable and, in a few states, put the principal at risk.
How is this different from investing in a private credit fund?
Scale, diversification and control. A fund spreads capital across many loans, employs credit analysts and lawyers, and hands you a passive interest in the pool after fees. A direct loan is one borrower, no diversification and no manager — you keep the whole spread and take the whole risk, and you do the underwriting, monitoring and any collection yourself.
