An earnest money promissory note is a written promise from a home buyer to deliver their earnest money deposit by a specific date shortly after signing the purchase contract, rather than handing over cash or certified funds at signing. Earnest money deposits in residential deals typically run 1% to 3% of the purchase price, and most sellers expect that money right away. The note is a short-term placeholder: it binds the buyer to pay, gives them a brief window to gather the funds, and lets the contract move forward in the meantime. It solves a narrow timing problem and comes with real trade-offs on both sides.
How It Differs From a Cash Deposit
In a standard transaction, the buyer sends earnest money as a cashier’s check, wire transfer, or certified funds shortly after the purchase agreement is signed. The escrow agent or title company deposits those funds and holds them until closing or until the deal ends under a valid contingency.
A promissory note replaces that immediate cash transfer with a legally enforceable IOU. The escrow agent holds the signed note instead of money. When the note matures, the buyer delivers the cash, the note is retired, and the escrow account is funded as if the deposit had been made on day one. Until that maturity date, the seller has a piece of paper, not money in escrow. That gap is why many sellers push back.
When Buyers Use One
The note exists to bridge timing gaps. A buyer might use one while waiting on proceeds from a stock sale that takes a few days to settle, a wire from an overseas account that hasn’t cleared, or a disbursement from another closing that’s scheduled but hasn’t happened yet. The buyer has the money, or will have it shortly, but can’t produce certified funds the day the contract needs to be signed.
In competitive markets where a desirable property attracts multiple offers within hours, even a two-day delay in producing earnest money can cost a buyer the deal. The note lets them execute the contract immediately and deliver funds once the transfer clears.
Both sides have to agree to this arrangement in writing, usually through an addendum to the purchase agreement that specifically authorizes a promissory note in place of immediate funds. Without that agreement, the default expectation is certified funds, and an escrow agent won’t accept a note on their own.
What the Note Should Contain
An earnest money promissory note has to work as a standalone enforceable document. Under the Uniform Commercial Code, a negotiable instrument must contain an unconditional promise to pay a fixed amount of money, be payable at a definite time, and be payable to a specific person or to bearer.1Legal Information Institute. UCC 3-104 – Negotiable Instrument An earnest money note follows that framework, tailored to a real estate deposit.
At minimum, the note should identify the buyer (the maker) and the party entitled to receive payment, which is usually the escrow agent or title company. It needs a precise dollar amount matching the earnest money required under the purchase agreement, and a specific maturity date when payment becomes due. In common practice that maturity date sits within a few days of contract execution, often 72 hours to a week.
The note should reference the underlying purchase agreement by property address and contract date, tying the instrument directly to the transaction it supports. A default clause spelling out what happens if the buyer fails to pay on time is essential. Most earnest money promissory notes carry zero interest, which is fine. The UCC explicitly allows negotiable instruments to be written “with or without interest.”1Legal Information Institute. UCC 3-104 – Negotiable Instrument
How Funding and Escrow Play Out
Once both parties sign the purchase agreement and the note, the buyer delivers the signed note to the escrow agent or title company. The escrow agent holds it as a placeholder for the deposit. The contract is binding during this window, but the escrow account contains no actual funds yet.
On or before the maturity date, the buyer sends the full amount in certified funds, a cashier’s check, or by wire transfer. The escrow agent deposits the money and marks the note as satisfied. The retired note is typically returned to the buyer as proof the obligation has been fulfilled. From there, the transaction proceeds exactly as if the buyer had delivered cash on day one. If the funds arrive on time, the note has no further legal effect.
What Happens If the Buyer Doesn’t Pay
If the buyer fails to deliver funds by the maturity date, the note becomes delinquent and the escrow agent notifies the seller. That creates a dual problem for the buyer: they’ve breached the note itself, and they’ve likely triggered the default provisions in the purchase agreement.
The seller’s remedies depend on what the purchase contract says. Common options include:
- Terminating the contract, canceling the deal, and relisting the property, treating the buyer’s failure to fund as a material breach.
- Suing the buyer directly on the note. Because the promissory note is an independent debt instrument, the seller doesn’t need to prove damages from a failed sale; the note itself establishes the debt.
- Keeping any partial cash deposit the buyer already delivered alongside the note, as liquidated damages under the contract terms.
Whether the seller can pursue more than one of these at the same time depends entirely on the purchase agreement. Some contracts treat the earnest money as liquidated damages and cap the seller’s recovery at that amount. Others preserve the right to sue for additional losses. Either way, a buyer who defaults on the note faces financial exposure for the full deposit amount even if the sale never closes. Signing the note is not a low-stakes gesture.
Why Sellers Often Push Back
From a seller’s standpoint, a promissory note is inherently less secure than cash already sitting in escrow. Cash is there. A note is a promise the cash will arrive later, and if the buyer can’t come through, the seller is left with an IOU they’d have to enforce through litigation. Most sellers don’t want to be in that position, especially in a market where other buyers are offering immediate deposits.
A buyer who can’t produce earnest money right away can also read as a financing risk, even when the actual reason is a mundane transfer delay. In a multiple-offer situation, a note almost always weakens the buyer’s competitive position against an offer with verified funds in hand.
Sellers who do agree to accept a note should insist on a short maturity period, a clear default clause, and language in the purchase agreement that specifically addresses what happens if the note isn’t honored. The shorter the maturity window, the less risk the seller absorbs.
Refunds and Contingencies Still Work Normally
Whether the earnest money is delivered as cash or promised through a note, the refund rules built into the purchase agreement still apply. If the buyer exits under a valid contingency, such as a failed inspection or a financing denial, the earnest money is returned to the buyer.2Legal Information Institute. Earnest Payment If the note hasn’t matured yet when the contingency triggers, the note is simply returned unfunded and the buyer owes nothing. If the buyer already funded the note before the contingency kicks in, the cash in escrow is refunded through the normal process. The form of the deposit doesn’t change the buyer’s contingency rights.
Where it gets complicated is when the buyer walks without a valid contingency. If all contingency deadlines have passed or been waived, the deposit is typically forfeited to the seller as liquidated damages. If the deposit was made by promissory note and hasn’t been funded, the seller holds a defaulted note and may need to pursue collection. That’s exactly the enforcement headache that makes sellers reluctant to accept notes in the first place.
A Note on Taxes
Because earnest money notes usually carry zero interest, buyers sometimes wonder whether the IRS’s below-market-loan rules under 26 U.S.C. ยง 7872 create a tax problem.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The short-term applicable federal rate is currently around 3.59% annually.4Internal Revenue Service. Rev. Rul. 2026-6 In practice this almost never matters. The note matures in days, not months, so any imputed interest would be negligible on a typical deposit. The note is also part of a purchase transaction rather than a gift or a true lending arrangement, so the imputed interest framework doesn’t cleanly apply. A short-term earnest money note at zero interest does not create tax consequences worth planning around.
