A wrap seller set the payoff window at month 36, and the buyer exercised it at month 14 with a cash refi, which left 22 months of spread income on the table.
The note was written with a five-year balloon and an early payoff right that kicked in after twelve months. The seller priced the rate at 7.5 over an underlying at 4.25, so 3.25 points on a 180,000 wrap. At full term that spread ran roughly 487 dollars a month. At month 14 the buyer refinanced, handed over the payoff figure, and the seller's yield on the whole deal landed nowhere near what the origination math suggested. The loss was not a default, not a servicer problem, and the buyer did nothing wrong. The seller simply wrote a payoff right without pricing it.
The fix is a yield maintenance clause or a prepayment premium structured to make the seller whole across a minimum hold period, usually 24 to 36 months of spread, whichever comes first. Some sellers add a declining premium schedule: full spread recapture in year one, half in year two, gone in year three. That still lets the buyer refi without a punishing penalty while protecting the seller from a 14-month exit on a note they wrote to run five years.
The deeper issue is that an early payoff right and a balloon are two different instruments, and sellers treat them as the same thing. A balloon forces the buyer to exit by a date. An early payoff right invites them to exit whenever it makes sense for them. Combine both without a yield floor and the seller is writing a call option on their own income stream.
How early was the payoff right in your note, and did the seller attach any premium language to it or leave it clean?
