Can a landlord use a promissory note for back rent?

Yes, and it is a common way to formalize a repayment plan. The tenant signs a note acknowledging a specific balance and promising to repay it on a defined schedule. That converts a disputed running balance into a fixed, dated debt with clear terms, which is considerably easier to enforce than arguing over a ledger later.

Does signing a note cancel the eviction case?

Only if you say so. This is the most important term in the document. In many states, accepting a payment on back rent can waive a pay-or-quit notice or reset the eviction clock. Your note should state plainly whether the pending case is dismissed, stayed while payments are current, or preserved, and whether the notice is waived. Silence here is what costs landlords their case.

Should the note include future rent too?

No. Keep the note to the arrears only, and let ongoing rent continue under the lease. Mixing them makes any later default ambiguous, because you cannot tell whether the tenant missed rent or missed a note payment, and the remedies for each are different. Two obligations, two documents, clean records.

Can I charge interest on unpaid rent?

Sometimes, and modestly. Two ceilings apply at once: landlord-tenant law in many states limits what can be charged on late rent, and your state usury cap limits interest on the note. Many landlords use a zero or low rate here, because the point is recovering the principal rather than profiting on it, and a high rate invites a challenge to the whole arrangement.

What is the real advantage over just tracking the balance?

The note survives the tenancy. Once the tenant moves out, a lease ledger becomes a claim you have to reconstruct, while a signed note is a standalone written contract with an admitted balance and terms. It also usually carries a longer limitations period than an oral or implied obligation, and a written acknowledgment of the debt strengthens collection.

Using a Promissory Note for Unpaid Rent

A tenant is three months behind, wants to stay, and offers to catch up over time. Taking that deal is often better business than an eviction, but a handshake repayment plan is worth almost nothing, and accepting payments carelessly can quietly destroy a pending eviction case. A promissory note fixes the first problem and, drafted properly, avoids the second.

What the note actually buys you

Back rent as a lease balance is a moving target: partial payments, disputed fees, and a ledger that has to be explained. A promissory note replaces all of that with a single acknowledged number and a schedule. The tenant signs that they owe a specific amount as of a specific date and will repay it on defined terms. Two consequences follow, and both favor the landlord:

The amount stops being arguable. A signed acknowledgment of the balance is hard to walk back later.
The debt outlives the tenancy. When the tenant moves out, the lease claim gets complicated while the note remains a standalone written contract you can sue on.

The clause landlords forget

This is the part worth slowing down for. In many states, accepting a payment toward back rent can waive a pay-or-quit notice or restart the eviction timeline, meaning a landlord who takes the tenant's first installment discovers their pending case has evaporated and they must serve a fresh notice and start over.

Your note must therefore say, explicitly, what happens to the eviction:

Whether the pending case is dismissed outright, stayed while payments stay current, or fully preserved.
Whether the pay-or-quit notice is waived, or expressly not waived.
What happens on default under the note: does the landlord resume the existing case, or start a new one?

Because this interacts with local eviction procedure, it is the one part of the arrangement worth a quick review by a local attorney if the balance is significant. For the related pattern on the notice side, see how tolerated late payments erode enforcement.

Keep arrears and ongoing rent separate

Put only the past-due balance in the note. Current rent keeps running under the lease. If you fold future rent into the note, every later default becomes ambiguous: did the tenant miss rent, which points toward eviction, or miss a note payment, which points toward a collection claim? The remedies differ, so keep the obligations in separate documents and separate ledgers.

Sizing it so it actually gets paid

A repayment plan the tenant cannot afford just delays the eviction by a month and costs you the notice. Realistic structuring:

Set the balance precisely, itemizing rent by month and any fees you are including.
Add the installment to ongoing rent and ask whether that total is plausible on their income. If it is not, shorten nothing and extend the term instead.
Keep interest low or zero. Two ceilings apply at once, landlord-tenant limits on charges for late rent and your state usury cap. See the maximum legal interest rate by state.
Include a modest late fee and an acceleration clause, so a missed installment makes the remaining balance due. See acceleration clauses.
Consider a co-signer for a large balance. See co-signer or guarantor on a note.

Running it afterward

Log every payment against the note separately from rent, with dates due and received. If you extend grace on an installment, put the accommodation in writing rather than letting a pattern develop; see how to document a deferral. And if the tenant leaves owing a balance, the note is what you take to small claims, where the signed acknowledgment does most of the work. See small claims court for unpaid notes and keeping a payment ledger.

For tenants offered one of these

Signing is often in your interest, since it usually means keeping your home, but read three things first: the total balance and whether you agree with it, whether the payment plus ongoing rent is genuinely affordable, and what the note says about the eviction case. You are signing a written acknowledgment of the debt, which is real and enforceable after you move out, so negotiate a schedule you can actually meet rather than the one that ends fastest.
