A promissory note in real estate is the document you sign that legally obligates you, personally, to repay a home loan on specific terms. When you finance a property, you sign two main documents at closing. The promissory note creates the debt. The mortgage (or deed of trust) pledges the house as collateral if you don’t pay. Most buyers focus on the mortgage, but the promissory note is where your financial obligation actually lives.
What the Note Contains
Every real estate promissory note spells out the same core terms. The principal is the total you’re borrowing. The interest rate is the cost of borrowing that money, and the note states whether that rate is fixed for the life of the loan or adjustable at set intervals. The maturity date is the deadline for the entire balance to be repaid. A payment schedule lays out how much you owe each month and when it’s due.
The note identifies the borrower (the maker) and the lender (the payee) by legal name. This matters more than it sounds. Only the people who sign the promissory note are personally liable for the debt. If two spouses buy a home together but only one signs the note, only the signer owes the money. The other spouse may have signed the mortgage, giving the lender a claim on the property, but carries no personal debt obligation.
Beyond the basics, the note sets out penalties and flexibility. Most include a late charge, often a percentage of the monthly payment, triggered after a grace period. The note also states whether you can prepay the loan early without penalty. That clause matters if you expect to refinance or sell before maturity.
Note vs. Mortgage
The promissory note and the mortgage are a matched pair that do different jobs. The note creates the debt. The mortgage secures it. Think of the note as your personal promise and the mortgage as the lender’s backup plan if you break that promise.
The mortgage (called a deed of trust in roughly half the states) pledges your property as collateral. It’s recorded in the county’s public land records, creating a lien that tells the world the lender has an interest in your home. The promissory note is not publicly recorded. The lender holds it privately as evidence of what you owe.
This split has real consequences. Because the note carries your personal liability, the lender can potentially pursue you for any remaining balance even after taking the property, depending on state law. The mortgage alone gives the lender only the right to foreclose on the house. Losing the property satisfies the mortgage lien, but it doesn’t automatically wipe out the debt created by the note.
Clauses That Catch Borrowers Off Guard
Acceleration Clause
Nearly every real estate promissory note includes an acceleration clause. If you violate certain terms, the lender can declare the entire remaining balance due immediately instead of continuing on the monthly schedule. The usual trigger is missed payments, but transferring the property without the lender’s consent can also set it off.
When a lender accelerates a loan, you receive a written notice demanding the full balance. Federal rules prevent lenders from jumping straight to foreclosure on missed payments alone. 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 exists so you can pursue alternatives like a loan modification or repayment plan.
Due-on-Sale Clause
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 mortgage without the lender’s approval. Almost every conventional mortgage includes this clause.
Federal law carves out important exceptions on a residential property with fewer than five units. Transfers to a spouse or children, transfers resulting from 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.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions If you move a property into a family trust for estate planning, for example, the lender cannot call your loan due.
Balloon Payment
Some promissory notes, especially in seller-financed deals, include a balloon payment. Your monthly payments are calculated as if the loan will stretch over 20 or 30 years, but the entire remaining balance comes due after a much shorter period, often five to seven years. The plan is usually to refinance before the balloon hits. That assumes you’ll qualify for refinancing when the time comes. If you can’t, the full balance lands all at once. Federal disclosure rules require lenders to show any balloon payment clearly in your loan paperwork, so read the payment schedule carefully 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 routinely sell promissory notes on the secondary market, bundling them and selling them to investors or government-backed entities like Fannie Mae. This frees up cash for the lender to make new loans. The terms of your note don’t change when it’s sold. Your interest rate, payment amount, and maturity date stay exactly 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 actually send payments to. When loan servicing transfers, the outgoing servicer must notify you at least 15 days before the transfer takes effect, and the new servicer must notify you within 15 days after.5eCFR. 12 CFR 1024.33 – Mortgage Servicing Transfers Read those notices carefully. The most common payment problem after a transfer isn’t a changed term; it’s a borrower sending a check to the old address.
Seller-Financed Notes
Promissory notes aren’t limited to bank loans. In a seller-financed deal, the property seller acts as the lender. You sign a promissory note directly with the seller, agreeing to make payments over time instead of paying the full price at closing. The seller typically records a mortgage or deed of trust just like a bank would, giving them the same foreclosure rights if you stop paying.
These arrangements offer flexibility a bank 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 carry balloon payments, and the interest rate is negotiated rather than set by market competition.
One tax wrinkle both parties should know: the IRS requires private loans to charge at least the Applicable Federal Rate (AFR). 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 than the AFR, the IRS treats the difference as a gift from lender to borrower, which can trigger gift tax consequences. The AFR changes monthly, so the rate in effect when the note is signed is the one that governs.
If You Default
A default happens when you violate the promissory note’s terms. Missing payments is the most common trigger, but failing to maintain homeowner’s insurance or letting property taxes go unpaid can also put you in default. Once you’re in default, the lender’s options escalate.
The lender will first send a breach letter, sometimes called a notice of default, informing you of the violation and giving you a window to fix it. If you’ve missed payments, the servicer still cannot begin foreclosure until you are more than 120 days behind.1Consumer Financial Protection Bureau. 12 CFR 1024.41 – Loss Mitigation Procedures During that period, the servicer must provide information about alternatives including loan modifications and repayment plans.
If the default isn’t resolved, the lender can foreclose. The specifics depend on your state. Some require the lender to go through court; others allow a faster out-of-court process. The property is eventually sold to satisfy the debt. A foreclosure will damage your credit score and remain on your credit report for seven years.
Deficiency Judgments
When a foreclosure sale doesn’t bring in enough to cover what you owe, the gap is called a deficiency. Whether the lender can come after you personally for that shortfall depends heavily on where you live. Roughly a dozen states prohibit or significantly restrict deficiency judgments on primary residences, including Arizona, California, and Washington. In states that do allow them, the amount the lender can collect is often capped at the difference between your loan balance and the property’s fair market value at the time of foreclosure, not the sale price. That distinction protects borrowers from lowball auction sales.
Statute of Limitations
Lenders don’t have forever to sue on a defaulted promissory note. Under the Uniform Commercial Code, which most states have adopted, the deadline to bring a lawsuit is six years from the due date stated in the note, or six years from the date the lender accelerated the loan.7Legal Information Institute. UCC 3-118 – Statute of Limitations Some states use shorter or longer periods, so check your state’s version. Once the statute of limitations expires, the lender loses the right to collect through the courts, though the debt itself doesn’t disappear.
When You Pay the Loan Off
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’s your proof that the debt is extinguished.
The lender must also release the lien on your property by filing a document, called a satisfaction of mortgage or a deed of reconveyance depending on your state, with the county recorder’s office. This clears the title and confirms no lender has a claim on your home. Most states set a deadline for filing this release, and penalties apply if the lender drags its feet.
If you had an escrow account for property taxes and insurance, the servicer must return any remaining balance within 20 business days of payoff.8Consumer Financial Protection Bureau. 12 CFR 1024.34 – Timely Escrow Payments and Treatment of Escrow Account Balances
