I never thought I’d be on the lending side of a financial transaction — I’d always been the one borrowing. That changed a few years ago when a close friend asked me to fund a short-term business loan at 9% interest. I said yes, we drafted a simple agreement with an attorney, and eight months later I’d made more on that $15,000 than I would have in a year of CDs. That experience sent me down a rabbit hole, and I’ve been exploring private lending in various forms ever since.
The reality is, lending money for profit isn’t just for banks. Individuals can participate at different levels, with different risk tolerances. Here’s what I’ve learned about the main approaches.
Peer-to-Peer Lending Platforms
P2P platforms like LendingClub and Prosper essentially let you act as the bank. You browse borrower profiles, see their credit grades, and fund portions of loans — sometimes as little as $25 per note, which makes diversification easy. The platforms handle all the paperwork, payment processing, and even collections if things go sideways.
I tried P2P lending with a modest amount spread across about 40 notes. Returns were solid in the early years, but defaults started hitting harder than the platform’s risk ratings suggested. That’s not unique to my experience — it’s the main knock against P2P lending. The platforms have gotten better at risk modeling, but you’re still taking on unsecured consumer credit risk. Don’t put in money you’d be stressed to lose.
Private Loans to Individuals or Small Businesses
This is what I did with my friend, and it’s also where most people get into trouble. Lending to someone you know feels low-risk because you trust them — but trust doesn’t guarantee repayment. You need a written contract. Full stop. Include the principal amount, interest rate, repayment schedule, and what happens in default. An attorney can draw one up for a few hundred dollars, which is a small price compared to losing the loan entirely.
Small businesses that can’t qualify for traditional bank loans can be good borrowers — they often pay a premium for flexibility and speed. But dig into their financials before you commit. Revenue trends, existing debt load, and whether the business has any real collateral all matter.
Real Estate Loans
Real estate lending — sometimes called “hard money” or private mortgage lending — is where many individual lenders end up because the loan is secured by property. If the borrower defaults, you can foreclose and recover. That backstop changes the risk calculus considerably.
I know someone who does second mortgages as a primary income stream. He lends at 7–9% on properties he’s personally walked through. His rule: only lend up to 65% of the property’s current value. That cushion protects him even if the market softens or the borrower misses months of payments. Real estate lending takes more work than throwing money into a P2P account, but the collateral makes it feel much more concrete.
Investing in Bonds
Bonds are technically you lending money to a corporation or government. When you buy a $10,000 Treasury bond, the federal government is the borrower. Corporate bonds work the same way, though you’re lending to a business instead.
Government bonds are the safest — you’re essentially lending to an entity that can print money — but the rates reflect that safety. Corporate bonds pay more because companies can actually go bankrupt. Municipal bonds fall somewhere in between and offer a nice perk: the interest is often exempt from federal taxes, which matters a lot if you’re in a higher bracket.
I keep a chunk of my fixed income allocation in a mix of intermediate-term Treasuries and investment-grade corporate bonds through Vanguard funds. Simple, low-cost, and they’ve done their job as a stabilizer when stocks get choppy.
Interest Rates and Profit Margins
The rate you charge needs to reflect actual risk. Charge too little and you’re leaving money on the table and potentially taking on risk that isn’t compensated. Charge too much and creditworthy borrowers walk away, leaving you with only the desperate ones.
Most private lenders I know start with benchmark rates — the fed funds rate, prevailing mortgage rates, whatever’s relevant — and add a premium for the credit quality of their specific borrower. A well-qualified small business owner might get 8–10%. Someone with shakier financials and no collateral should be paying considerably more, or you probably shouldn’t be lending to them at all.
Risk Management
Diversification is the core principle. If you lend $50,000 to a single borrower and they default, you’re in pain. If you spread that same $50,000 across 20 different loans, a single default is a setback, not a disaster.
Collateral is your other main protection. Loans secured by real property, equipment, or business assets are fundamentally different from unsecured personal loans. When I’m evaluating a private lending opportunity, I ask: what happens if this borrower can’t pay? If the answer is “I get nothing,” I need the rate to be high enough to compensate for that, or I pass.
Legal Considerations
Usury laws cap the interest rates you can legally charge, and they vary by state. In some states the limits are generous; in others, rates above 10–12% can get you into trouble. If you’re charging high rates on unsecured consumer loans, you may also need a lending license. This stuff matters — operating outside these rules exposes you to legal risk that can wipe out any profit you made.
Anti-discrimination laws apply to private lenders too, not just banks. Your lending decisions need to be based on financial criteria, not anything protected under fair lending statutes.
Monitoring and Collections
Set up automatic payment reminders at the very least. For larger loans, I’d recommend monthly check-ins with the borrower. Catching problems early — a missed payment, a struggling business — gives you time to restructure the loan rather than pursue collections, which is expensive, slow, and often recovers far less than face value.
If a borrower does go delinquent, communicate early and often. Most people who miss payments aren’t trying to steal your money — they’re just struggling. Working out a modified payment plan is usually better for both sides than the alternative.
Practical Examples
Here’s the math on a straightforward private business loan: $10,000 at 8% over five years works out to monthly payments of about $202.76. Total repayment comes to roughly $12,166 — a profit of $2,166 on your original $10,000. Not life-changing, but that’s also a relatively small loan at a conservative rate.
Scale that up: $50,000 as a second mortgage at 7% over 10 years generates monthly payments around $581. Over the life of the loan, you collect about $69,720 — nearly $20,000 in interest. And the whole time, you have the property as collateral. That’s what makes real estate lending attractive for people who want meaningful cash flow from their capital.
The Emotional Side
One thing the financial calculations don’t capture: lending money to people you know is emotionally complicated. I’ve seen friendships strained and family dynamics upended by informal loans gone wrong. If you’re going to lend to someone in your personal life, treat it as professionally as you would a stranger. Contracts, documentation, clear terms. Or consider whether a gift would be less damaging to the relationship if things go poorly.
Private lending can be a genuinely profitable way to put capital to work. The key is being honest about the risks, protecting yourself with documentation and collateral where possible, and never lending money you can’t afford to have tied up — or, in a worst case, to lose.
