Selling a Partial Note
A partial note sale transfers a fractional interest in a payment stream to a new counterparty while you retain a residual interest in the same instrument. Two counterparties share the future payments, two counterparties share the servicing work, and the present-value math splits across the partial-interest split the closing package carries. Below is the lender-independent walk-through of how the math, the paperwork, and the day-to-day mechanics actually work.

The short answer
Three honest answers to one question
Note holders search this question a few different ways. Each one is the same question viewed from a different angle — the short answer is the same in all three.
What is a partial note?
A partial note is a fractional interest in the same payment stream — for example, half of a $50,000 first-lien mortgage note, or any of four slices of a larger seller-carryback position. Each slice comes with its own pro-rata entitlement to every monthly payment and to the collateral enforcement that follows any default. The note itself is the same legal instrument; the partial interest is a contractual interest in that instrument.
What it means to sell a partial interest
Selling the partial interest transfers every pro-rata right you hold to a new counterparty. That counterparty steps into the same receipt role on every future payment, picks up its share of the servicing work, and inherits its pro-rata share of any collateral recovery if the borrower defaults. You walk away from your share of the stream — the remaining payments on your fraction stop arriving at your account — and you receive a lump sum in exchange.
How a partial sale is different from a whole-stream sale
In a whole-stream sale the entire payment stream changes hands in one assignment; the seller has zero ongoing relationship with the borrower and the buyer takes 100% of the future cash flow plus 100% of the servicing work. In a partial sale two counterparties stay on the books — the seller keeps its residual interest, the buyer takes its purchased slice, and both sides share the servicer and any default logistics from that point on.
A partial sale keeps you on the books alongside the buyer — you walk away from your slice and keep your residual interest. If your goal is a complete exit instead, a whole-stream sale is the cleaner path; if your goal is liquidity without giving up every future payment, a partial sale does exactly that.
The honest math
A worked first-lien partial-interest example
Imagine you are holding a first-lien mortgage note on a single-family property: $50,000 unpaid balance, 8% interest rate, 36 monthly payments remaining. The borrower is current, the seasoning is comfortable, and the file sits in good shape. You want to keep a residual interest so a partial sale is the structure.
The math is straightforward: apply a discount rate to every remaining payment to convert the stream into a present value, then apply a buying-spread haircut to that number. Then carve out the partial-interest slice you are transferring — the buyer pays the slice's share of the present-value figure, the rest of the cash flow stays on your books.
| Buyer-spread haircut | Offer on the whole stream (today) | Offer on a 50% partial-interest slice |
|---|---|---|
| ≈15% haircut | about $44,000 | about $22,000 |
| ≈25% haircut | about $39,500 | about $19,750 |
| ≈33% haircut | about $35,300 | about $17,650 |
The discount rate drives the present-value math; the buying-spread drives the offer; the partial-interest slice splits the offer. Direct-acquisition economics (one counterparty relation, no intermediary in the middle) hold whether you are selling the whole stream or just your share of it.

What stays, what walks
Three sides of a partial-interest closing
A partial sale is not a whole sale plus a refund stub — it is a different instrument structure with a different end-state. The three groupings below cover what changes at closing, what stays in place, and how the math splits across the two counterparties that remain on the books.
Stays on the books
Your residual interest in the same instrument. You remain a co-payee on every future payment, you retain your pro-rata share of any workout or collateral recovery, and your share keeps producing cash flow on the schedule that the note already runs on.
Walks at closing
Your right to receive your share of the future payment stream — the buyer takes that on the assignment date. Your servicing work shifts to the same servicer arrangement the buyer uses, the buyer pays its share of any third-party closing cost out of its discount, and your share of the default-protection posture switches from "your file" to "your file alongside the buyer."
Splits at the underwriting table
Two counterparties reading the same set of inputs end up with two pro-rata slices of the same offer. The discount rate, the buying-spread, the BPO valuation, and the title work are all evaluated once; the math is then divided across the partial-interest split that the closing package carries. There is no second underwriting cycle and there is no second buyer in the middle.
How a partial sale actually happens
Four steps from inquiry to wire
The closing pipeline for a partial-interest sale is the same shape as a whole-stream sale — share the unpaid balance, the rate, the payment history, the property details, and the partial-interest split. Underwriting pulls a valuation and writes the offer for the slice being sold, the buyer accepts, the transfer documents are prepared, and the wire lands once the closing package clears.

Run the numbers yourself
Quote the present value before you commit
The same discount-rate framework that powers a whole-stream quote powers the present-value read on a partial-interest slice. The calculator on the request form runs the math against your payment schedule; the offer you receive is the partial- interest slice of that number, prorated to the share you are transferring.
