An earnest money promissory note is a written promise from a home buyer to deliver the earnest money deposit by a specific near-future date instead of handing over cash or certified funds the moment the purchase contract is signed. It’s a short-term placeholder, usually maturing within a few days to a week, that lets the buyer lock in the deal while they wait on funds that haven’t yet cleared. The note is legally enforceable, so the buyer takes on a real obligation. The seller, meanwhile, holds a piece of paper rather than money in escrow until the note is paid.
How It Differs From a Cash Deposit
In a standard residential transaction, the buyer wires funds or delivers a cashier’s check shortly after the purchase agreement is executed, and the escrow agent or title company parks that money in an escrow account until closing. Earnest money typically runs 1% to 3% of the purchase price.
With a promissory note, the escrow agent holds the signed note instead of cash. On the maturity date, the buyer delivers the funds, the note is retired, and the escrow account is funded as if the deposit had arrived on day one. Until that date, there is no money in escrow, only a legally enforceable IOU. That gap is the whole reason the arrangement is uncommon.
When Buyers Use One
The note solves timing problems, not funding problems. Common scenarios include waiting on proceeds from a stock sale that takes a few days to settle, an overseas wire that hasn’t cleared, or a disbursement from another closing that’s scheduled but hasn’t happened. 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 a competitive market, even a two-day delay in producing earnest money can cost a buyer the property. The note lets the buyer execute the contract immediately and deliver cash once the transfer clears. Both parties must agree to this in writing, usually through an addendum to the purchase agreement that specifically authorizes a note in place of immediate funds. An escrow agent won’t accept one on their own initiative; the default expectation is certified funds.
What the Note Must Contain
The note needs to function 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
Working from that framework, the note should include:
- The buyer’s name as maker and the party entitled to receive payment, usually the escrow agent or title company.
- A precise dollar amount matching the earnest money required under the purchase agreement.
- A specific maturity date, commonly 72 hours to a week after contract execution.
- A reference to the underlying purchase agreement by property address and contract date, tying the note to the transaction it supports.
- A default clause spelling out what happens if the buyer fails to pay on time.
Most earnest money notes are written at zero interest, which is fine. The UCC allows negotiable instruments to be written “with or without interest.”1Legal Information Institute. UCC 3-104 – Negotiable Instrument
How Payment and Escrow Play Out
Once both parties sign the purchase agreement and the note, the buyer delivers the signed note to the escrow agent. The contract is binding, but the escrow account holds no actual funds during this window.
On or before the maturity date, the buyer sends the full amount by wire, cashier’s check, or other certified funds. The escrow agent deposits the money, marks the note satisfied, and typically returns the retired note to the buyer as proof the obligation is fulfilled. From there, the transaction proceeds exactly as if cash had been delivered on day one. If the funds come in on time, the note has no further legal effect.
What Happens if the Buyer Doesn’t Pay
Missing the maturity date puts the buyer in a difficult spot. The note itself is in default, and the failure to fund usually triggers the default provisions in the purchase agreement as well. The escrow agent notifies the seller, and the seller’s options generally include:
- Terminating the contract and relisting the property, treating the funding failure as a material breach.
- Suing the buyer directly on the note. Because the note is an independent debt instrument, the seller doesn’t have to prove damages from a failed sale; the note itself establishes the debt.
- Keeping any partial cash deposit that was delivered alongside the note, if the contract treats earnest money as liquidated damages.
Whether the seller can combine these remedies depends on the purchase agreement. Some contracts cap recovery at the earnest money as liquidated damages; others preserve the right to sue for additional losses. Either way, a buyer who defaults on the note is exposed for the full deposit amount even though the sale never closed.
Why Sellers Often Say No
From the seller’s side, a note is less secure than cash in escrow. Cash is already there. A note is a promise, and if the buyer can’t come through, the seller is left enforcing an IOU through litigation. In a market where other buyers are offering immediate deposits, that’s rarely attractive.
Buyers who can’t produce earnest money immediately may also signal financing uncertainty, even when the real reason is a mundane transfer delay. In a multiple-offer situation, a note almost always weakens the buyer’s competitive position compared to an offer backed by verified funds. Sellers who do agree should insist on a short maturity, a clear default clause, and contract language that specifically addresses what happens if the note isn’t honored.
Refunds and Contingencies Still Apply
The form of the deposit doesn’t change the buyer’s contingency rights. 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, it’s simply returned unfunded and the buyer owes nothing. If the note was already funded before the contingency triggered, the cash is refunded through the normal escrow process.
The complication is a buyer who walks without a valid contingency after deadlines have passed or been waived. The deposit is typically forfeited to the seller as liquidated damages. If the deposit was promised by note and never funded, the seller holds a defaulted instrument and may have to sue to collect, which is the enforcement headache that makes sellers wary of accepting notes to begin with.
A Note on Zero Interest and Taxes
Buyers sometimes ask whether a zero-interest note creates imputed-interest problems under IRS rules on below-market loans. In theory, 26 U.S.C. ยง 7872 can apply to interest-free loans.3Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The applicable federal rate for short-term loans is currently around 3.59% annually.4Internal Revenue Service. Rev. Rul. 2026-6
In practice this doesn’t matter for earnest money notes. The maturity runs in days, so any imputed interest on a typical deposit would be negligible, and the note is part of a purchase transaction rather than a loan in the usual sense. Buyers and sellers using a short-term earnest money note at zero interest don’t need to plan around tax consequences from the note itself.
