A balloon note amortizes like a normal loan for a while, then the whole remaining balance comes due at once.
How the schedule works
The loan follows its normal payment schedule (amortizing or interest-only) up to the balloon point; the final row then balloons the remainder — the entire outstanding balance plus that period's interest. The balloon composes with the loan's other terms (interest type, rate riders, day-count), so the schedule you preview is the schedule you service.
Balloon notices
You'll never be surprised by a maturing balloon. NoteHarbor surfaces escalating reminders at 12 months, 6 months, 90 days, 60 days, and 30 days before the balloon date (and flags one that's past due). They appear on the dashboard's balloon notices, so an approaching balloon is visible every time you open the app.
Extensions
Agreed to give the borrower more time? An extension moves the balloon date — the reminders re-anchor to the new date and the loan's balloon metadata follows along, including through loan modifications.
Guarded term edits
Because the balloon is derived from the loan's terms, term edits on balloon loans are guarded — changes that would silently break the balloon structure are rejected with a clear message instead of producing a schedule that no longer matches the note.
Balloon loans with a matured balloon can't be shared to an investor's workspace — the share is refused clearly rather than creating a divergent copy.
