A promissory note in real estate is the signed document that creates your personal legal obligation to repay a home loan under specific terms. When you finance a property, you sign two separate documents at closing: the promissory note, which is your binding promise to repay a set amount on a set schedule, and the mortgage or deed of trust, which pledges the property as collateral if you don’t. The mortgage gets the attention. The note is where your debt actually lives.
What the Note Says
Every real estate promissory note covers the same core ground. The principal is the amount you’re borrowing. The interest rate states the cost of that money and specifies whether it’s fixed for the life of the loan or adjustable at set intervals. The maturity date is the deadline for full repayment. A payment schedule sets out how much is due and when.
The note also names the borrower (the maker) and the lender (the payee) by their legal names. This matters more than it appears. Only the people who sign the note are personally responsible for the debt. If two spouses buy a home together but only one signs the note, only the signer is legally liable for repayment. The non-signing spouse may still be on the mortgage, giving the lender a claim on the property, but carries no personal debt obligation.
Beyond the numbers, the note handles penalties and flexibility. Most include a late charge, typically a percentage of the monthly payment when it arrives after a grace period. The note also states whether you can prepay without a penalty, which matters if you plan to refinance or sell before maturity.
How the Note Differs From the Mortgage
The note and the mortgage are a matched pair doing different jobs. The note creates the debt. The mortgage secures it.
The mortgage (called a deed of trust in roughly half the states) pledges your property as collateral and gets recorded in the county land records, creating a public lien. The promissory note is not recorded. The lender holds it privately as evidence of what you owe.
The consequence is real. Because the note carries your personal liability, a lender may be able to pursue you for a remaining balance even after taking the property, depending on state law. The mortgage alone only gives the lender the right to foreclose. Losing the property satisfies the mortgage lien but doesn’t automatically wipe out the debt created by the note.
Clauses to Read Carefully
Acceleration
Nearly every real estate promissory note contains an acceleration clause. If you violate certain terms, the lender can declare the entire remaining balance due immediately instead of continuing the monthly schedule. The common trigger is missed payments, though transferring the property without the lender’s consent can also set it off.
When a lender accelerates, you receive written notice demanding the full balance. Federal rules keep lenders from jumping straight to foreclosure over missed payments. A servicer cannot file the first foreclosure notice until you are more than 120 days delinquent.1Consumer Financial Protection Bureau. 12 CFR 1024.41 – Loss Mitigation Procedures That window gives you time to work out a loan modification or repayment plan.
Due-on-Sale
A due-on-sale clause lets the lender demand full repayment if you sell or transfer the property. Without one, a buyer could theoretically take over your loan without lender approval. Almost every conventional mortgage includes this clause.
Federal law carves out exceptions on residential property with fewer than five units. Transfers to a spouse or children, transfers under a divorce decree, transfers into a living trust where you remain a beneficiary, and transfers after the death of a co-borrower are all protected from enforcement.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions Moving a property into a family trust for estate planning, for example, does not give the lender grounds to call the loan.
Balloon Payments
Some notes, especially in seller-financed deals, include a balloon payment. Monthly payments are calculated as if you’re paying the loan off over 20 or 30 years, but the entire remaining balance comes due much sooner, often after five to seven years. The assumption is that you’ll refinance before the balloon hits. If you can’t qualify to refinance when the time comes, you owe the whole balance at once. Federal disclosure rules require the balloon to appear clearly in your loan paperwork, so read the payment schedule before signing.3Consumer Financial Protection Bureau. 12 CFR 1026.17 – General Disclosure Requirements
Your Note Can Be Sold
The lender you close with often won’t hold your note for long. Lenders sell promissory notes on the secondary market, bundling them and selling to investors or entities like Fannie Mae, which frees up cash for new lending. The terms of your note don’t change when it’s sold. Your interest rate, payment amount, and maturity date stay the same.4Consumer Financial Protection Bureau. What Happens if My Mortgage Is Sold? Is My Loan Safe?
What can change is the servicer, the company you send payments to. When servicing transfers, the outgoing servicer must notify you at least 15 days before the transfer, and the new servicer must notify you within 15 days after.5eCFR. 12 CFR 1024.33 – Mortgage Servicing Transfers Watch those notices. The most common payment problem after a transfer isn’t a changed term; it’s a borrower mailing a check to the old address.
Seller-Financed Notes
Promissory notes aren’t limited to bank loans. In a seller-financed deal, the seller acts as the lender. You sign a note directly with them, making payments over time instead of paying the full price at closing. The seller typically records a mortgage or deed of trust, giving them the same foreclosure rights a bank would have.
These arrangements offer flexibility banks can’t match. Closing costs tend to be lower, the qualification process is simpler, and the terms are negotiable. The flexibility cuts both ways. Seller-financed notes are more likely to include balloon payments, and the interest rate is negotiated rather than shaped by market competition.
Both parties should know one tax rule: the IRS requires private loans to charge at least the Applicable Federal Rate. For March 2026, the long-term AFR (for loans over nine years) is 4.72% with annual compounding.6Internal Revenue Service. Revenue Ruling 2026-6 – Applicable Federal Rates If the note charges less, the IRS treats the difference as a gift from lender to borrower, which can trigger gift tax consequences. The AFR changes monthly, and the rate in effect when the note is signed is the one that matters.
What Counts as Default
A default is a violation of the note’s terms. Missed payments are the most common trigger, but failing to maintain homeowner’s insurance or letting property taxes go unpaid can also put you in default.
The lender will send a breach letter, sometimes called a notice of default, identifying the violation and giving you a window to cure it. If you’ve missed payments, federal rules add another layer: the servicer cannot begin foreclosure until you’re more than 120 days behind, and during that period must provide information about alternatives including loan modifications and repayment plans.1Consumer Financial Protection Bureau. 12 CFR 1024.41 – Loss Mitigation Procedures
If the default isn’t resolved, the lender can foreclose. Some states require the lender to go through court (judicial foreclosure), while others allow a faster out-of-court process (nonjudicial foreclosure). Either way, the property is eventually sold to satisfy the debt. Because the note carries personal liability separate from the mortgage, in states that allow it a lender may pursue a deficiency judgment for any balance the sale doesn’t cover.
What Happens at Payoff
When you make your final payment, the lender must cancel the promissory note and return it to you marked paid in full. Keep that canceled note. It is your proof the debt is extinguished.
The lender must also release the lien on your property by filing a satisfaction of mortgage or deed of reconveyance (the name depends on your state) with the county recorder. That clears the title and confirms no lender has a claim on the home. Most states set a deadline for filing this release, with penalties for delay.
If you had an escrow account for property taxes and insurance, the servicer must return any remaining balance within 20 business days of payoff.7Consumer Financial Protection Bureau. 12 CFR 1024.34 – Timely Escrow Payments and Treatment of Escrow Account Balances The exception is a refinance with the same lender or servicer, where you can agree to roll the escrow balance into the new loan instead of taking a refund.
