What Is a Promissory Note? The Core Document Behind Every Private Real Estate Loan

Every private real estate loan rests on two foundational documents: the promissory note and the deed of trust. The deed of trust gives the lender the right to foreclose on the property if the borrower defaults. The promissory note creates the debt itself — the legally enforceable obligation to repay. When you invest in a private lending fund like LBC Capital, the fund holds a portfolio of these notes on your behalf. Understanding what a note actually contains, and how its provisions play out in practice, is understanding what you actually own as an investor.

The Eight Essential Provisions in a Promissory Note

A commercial promissory note typically spells out: the principal amount (the face value of the debt); the interest rate, fixed or variable; payment terms — when interest is due and whether the loan is interest-only or amortizing; the maturity date; prepayment terms, including whether early repayment carries a cost; default provisions defining what triggers a default and what the lender can do about it; a personal guarantee provision stating whether the loan is recourse or non-recourse; and the governing law clause specifying which state’s law controls any dispute. Each of these gets negotiated at origination and locked in for the life of the loan.

The Note vs. the Deed of Trust: Two Documents, One Loan

The note and the deed of trust work as a paired set, and the distinction matters more than it might seem. The note is the borrower’s unconditional promise to repay — it creates the personal obligation. The deed of trust is the security instrument: it pledges specific real property as collateral for that same obligation. If the borrower defaults, the note gives the lender a claim against the borrower personally on a recourse loan, while the deed of trust gives the lender the right to foreclose on the specific property. A complete, enforceable first-lien private real estate loan needs both documents working together — one without the other leaves a real gap in the lender’s position.

Fixed Rate vs. Variable Rate Notes

Most private bridge loans carry fixed interest rates for the full loan term — the note states something like “Borrower promises to pay interest at the rate of 10.00% per annum on the unpaid principal balance,” and that rate doesn’t move regardless of what happens in the broader rate environment. Some private loans use variable rates instead, expressed as a spread over a benchmark — “Prime Rate + 3.50%” or “SOFR + 4.00%” are both common, with SOFR now the standard benchmark following LIBOR’s phase-out. Variable rate notes adjust periodically, monthly or quarterly, and can raise a borrower’s payment meaningfully if rates climb during the loan term. Most private bridge borrowers prefer the payment certainty of a fixed rate; most lenders are comfortable with either structure at a comparable yield.

Prepayment Terms: What Actually Happens When a Borrower Repays Early

Private real estate notes almost always include some form of prepayment protection, compensating the lender when a borrower repays ahead of schedule. Common structures include a minimum interest guarantee (the borrower owes a set number of months of interest even if the loan is repaid in month one), a step-down penalty (a shrinking percentage of the outstanding balance — 3% in month one, 2% in month two, 1% in month three, nothing after that), or yield maintenance, which compensates the lender for the economic value of the payments it would otherwise have received.

Worth being precise about the arithmetic here, since it’s easy to overstate: on a $1.8 million note at 10% with a three-month minimum interest guarantee, the total guaranteed interest over that window is $45,000 ($1.8M × 10% × 3/12). But if the borrower has already made a regular monthly interest payment before prepaying — say, roughly $15,000 for month one — a well-drafted note credits that payment against the guarantee, so the amount actually due at a month-two payoff is the remaining shortfall, closer to $30,000, not a fresh $45,000 on top of what’s already changed hands. Ask specifically whether a fund’s notes credit interest already paid against the minimum guarantee; it’s a detail that changes the real economics of an early payoff.

Default Provisions: What Triggers Acceleration

A note’s default provisions define the events that let the lender declare the full balance immediately due — “acceleration.” Common triggers include a payment default, commonly after a short grace period (grace periods vary by note, but something in the 5-to-15-day range is typical); an insurance lapse; an unauthorized transfer or encumbrance of the property without lender consent; material misrepresentation during underwriting; physical waste or neglect of the collateral; and borrower bankruptcy, which most private loan notes list as an automatic event of default.

That last one deserves a real caveat. A note can say bankruptcy triggers automatic acceleration, but the moment a borrower actually files, the federal automatic stay under 11 U.S.C. § 362 takes effect immediately and blocks the lender from acting on that acceleration — sending default notices, foreclosing, or exercising most other remedies — without first going to the bankruptcy court for relief from the stay. The contractual trigger is real, but enforcing it in practice means a court filing and a waiting period, not an automatic, same-day right. A fund’s documented default-and-workout process, the kind our loan committee framework is built around, is what actually determines how quickly that gets resolved in practice.

Endorsement and Transfer of Notes

Promissory notes are negotiable instruments under the UCC — they transfer from one holder to another through endorsement, similar to endorsing a check. When a private lending fund holds a note, the fund entity is named the “holder of record” or “payee.” If the fund ever sells a loan on the secondary market, the note has to be properly endorsed and physically transferred. The chain of endorsements on the back of the note documents every transfer, and a broken link in that chain — a missing endorsement from a prior transfer — doesn’t just create paperwork friction. It can genuinely complicate the current holder’s ability to prove standing to enforce the note if a borrower’s attorney challenges it, which is exactly the scenario a fund wants to avoid walking into during a contested foreclosure. Notes held in independent custody, with a clean, documented chain, are the safer structure.

What Investors Should Know About the Note Portfolio Backing Their Investment

As a fund investor, you don’t hold individual notes directly — the fund does, and your investment is ultimately backed by whatever is actually in that portfolio. Worth asking directly, of LBC Capital or any fund you’re evaluating: can the fund provide a loan tape listing every note’s terms, LTV, maturity date, and payment status? Are notes held in independent custody, or stored by the manager itself — the same governance question our piece on what happens if a fund manager fails walks through in more depth? Has the fund ever had a note with a title or endorsement defect that needed legal correction? The specificity of the answer tells you more than the answer itself — a manager who can walk through their custody and endorsement practices in detail is managing the legal infrastructure behind the portfolio deliberately, not just assuming it takes care of itself.

Frequently Asked Questions

What’s the real difference between a promissory note and a deed of trust?

The note creates the debt — the borrower’s promise to repay. The deed of trust secures that debt against a specific property, giving the lender a foreclosure right if the borrower defaults. They’re always used together in a private real estate loan; neither one alone gives a lender a complete, enforceable position.

If I prepay a loan with a minimum interest guarantee, do I pay the full guaranteed amount on top of what I’ve already paid?

Not under a well-drafted note. The minimum interest guarantee states a total amount owed over a set window, and interest already paid during that window is normally credited against it — so what’s actually due at payoff is the shortfall, not a duplicate charge. It’s worth confirming this explicitly, since not every note is drafted the same way.

Does a borrower’s bankruptcy filing let the lender foreclose right away?

No, even though most notes list bankruptcy as a default event that triggers automatic acceleration. The federal automatic stay stops the lender from acting on that acceleration the moment a bankruptcy case is filed, and the lender has to get the bankruptcy court’s permission — relief from the stay — before resuming collection or foreclosure. The contractual trigger is immediate; the actual enforcement timeline is not.
