Note income for a mortgage is the monthly payment a borrower receives on a promissory note, most often from selling a property with seller financing. Lenders verify it with a copy of the note and twelve months of on-time payments, usually shown as deposits on bank statements. The note must also have at least three years of payments left.
What proves note income for a mortgage?
Note income is proved by two things: the note itself, which sets the amount and length of the payments, and a record of the payments actually arriving. The Fannie Mae Selling Guide section on notes receivable income asks for a copy of the note and evidence of receipt for the most recent 12 months.
The guide accepts bank statements, canceled checks and electronic payment records as evidence of receipt. It also asks that the history show full, regular and timely payments. Of the three, bank statements are the most common, because the borrower already supplies them for assets.
What to read on the note
- Payment amount. The monthly figure the lender will compare with deposits.
- Payment date. The day each payment is due, which sets the window for each deposit.
- Maturity date and any balloon. The date the note ends or the balance comes due in one sum.
- Payer. The buyer's name, which should match the deposit description or the canceled checks.
Seller financing payments across twelve months of bank statements
Seller financing payments appear on bank statements as one deposit a month from the buyer, close to the due date and for the amount in the note. The lender builds a log that sets each deposit beside the scheduled payment. Twelve rows that match, or nearly match, satisfy the history test. Rows that do not match need a reason.
Example payment log
The log below is an example. The note calls for $1,450 on the 1st of each month.

|---|---|---|---|---|
| Nov 2025 | $1,450 | Nov 1 | $1,450 | On time |
| Dec 2025 | $1,450 | Dec 2 | $1,450 | On time |
| Jan 2026 | $1,450 | Jan 2 | $1,450 | On time |

Eleven payments arrived within a few days of the due date. The March payment arrived eighteen days late. A lender will ask about it, and the answer decides whether the history still counts as timely.
When the payer uses a servicer
Some sellers hire a loan servicing company to collect from the buyer. Then the deposit names the servicer, not the buyer, and the servicer's payment history may serve as the electronic payment record. When no bank statement shows the payments at all, a lender may ask the borrower's bank to confirm the account in writing, a process described in the verification of deposit form.
Why is a note signed within the last year excluded?
A note signed within the last year is excluded because it lacks twelve months of payments. The Fannie Mae guide states that payments on a note executed within the past 12 months may not be used as stable income, whatever its length. A thirty-year note signed six months ago does not count until it has a year of history.
The rule surprises sellers who carry back financing to help a buyer, then apply for their own mortgage soon after. The sale proceeds may help with the down payment, but the monthly note payment cannot qualify them yet. Money received from the sale itself, as a one-time profit, is a separate question covered in capital gains income for a mortgage.
Note income continuance and the remaining note term
Continuance for note income means the payments are scheduled to last at least three years from the application date. The lender reads the maturity date on the note and counts forward. A note that matures or balloons within three years fails the test, even if every payment so far has been on time.
Balloon notes
Many seller-financed notes amortize over a long period but come due in a balloon after five or seven years. The monthly payment counts only if the balloon date is at least three years away. Once the balloon is closer than that, the note income no longer qualifies, though the expected payoff may later count as an asset.
Early payoff risk
A buyer may refinance and pay off the note early. Lenders generally rely on the note's terms rather than guess at refinancing. A buyer who has told the seller they are refinancing next month is a different case, and a borrower who knows that should say so.
Other small rental-style income streams use a similar receipt-and-continuance logic, such as rent from a lodger, explained in boarder income for a mortgage when renting a room.
Late or partial note payments in the deposit record
Late or partial note payments weaken the income because the guide asks for full, regular and timely payments. One late payment with a clear reason may be accepted. A pattern of late or short payments suggests the buyer may default, and the lender may exclude the income or ask for a longer history.
How to handle each case
- One late payment. Get a short explanation and evidence it was made up in full.
- Partial payments. Compare the total received with the total due. A shortfall usually disqualifies the income.
- Catch-up payments. Two payments in one month after a missed one show the buyer caught up, but the record is no longer regular.
- Payments into different accounts. Collect statements for each account so the log has no blank months.
TrueBankFlow groups deposits from the same payer on a regular schedule and shows their cadence and average amount, so a note payment that arrives late or short stands out against the other months. See how recurring income is grouped.
