Selling a Promissory Note: Discounts, Note Buyers and Taxes

By Hans Goldstein · Updated 2026-09-27

Yes, you can sell a promissory note you received from seller financing, but you will almost always sell it at a discount. A note buyer pays the present value of the remaining payments at the yield it wants, which is usually well above your note's rate. For tax, selling the note is a disposition under IRC §453B: the remaining deferred gain is reported in the year you sell, measured by the price you receive minus your basis in the note.

This article covers how note buyers price your note, full versus partial sales, how to prepare, and what the sale does to your taxes.

Why sellers sell their notes

The usual reasons: a large expense or investment, a buyer whose payments have become unreliable, an estate that does not want to administer a 20-year note, or simply wanting certainty over waiting. Each is legitimate. The cost is the discount, plus losing the tax deferral that made seller financing attractive.

Before selling, compare the alternatives: a refinance of the buyer (which pays you at face value), a negotiated early payoff at a small discount, or keeping the note and managing risk.

How note buyers price a promissory note

A note buyer, sometimes called a private mortgage note buyer, is buying a stream of payments. The price is the present value of those payments at the buyer's required yield. The yield rises with risk, and these are the factors that drive it:

Factor Lower discount Higher discount
Payment history (seasoning) 12 or more months of on-time payments New note or late payments
Payer's credit Strong credit, stable income Weak or unknown credit
Equity Large down payment, low balance vs value Thin equity
Collateral Owner-occupied home or well-located property Vacant land, rural or special-use property
Lien position First lien Second lien behind a bank
Note rate vs market Rate near or above market Rate well below market
Term remaining Short Long (more time for things to go wrong)
Documents Recorded deed of trust or mortgage, title policy, clean payment records Missing originals, unrecorded lien, informal records

There is no published schedule of discounts. Get more than one quote, ask each buyer what yield it is pricing to, and read the term sheet for fees and conditions.

Simple example: pricing the discount

Simple example. Assumptions: your note has an unpaid balance of $300,000 at 6.5%, with 20 years (240 monthly payments) remaining. The monthly payment is $2,236.72. A note buyer offers a price that gives it a 10% yield.

Item Amount
Remaining payments 240 x $2,236.72
Unpaid principal balance $300,000
Price at a 10% yield $231,779
Discount from the balance $68,221 (about 23%)

The discount is not a fee. It is the difference between your 6.5% note and the buyer's 10% target, compounded over 20 years. A shorter remaining term or a higher note rate shrinks it.

Full sale vs partial sale

Full note sale Partial purchase
What you sell All remaining payments A set number of payments, for example the next 60
Cash now Highest Lower
Discount Usually largest Usually smaller, since the buyer's risk is shorter
After the partial term Nothing comes back Payments revert to you
Tax Full §453B disposition Disposition of the portion sold; allocation of basis should be worked out with your CPA

Continuing the example: the next 60 payments total $134,203. At the same 10% yield, their present value is about $105,272. You would receive that now and resume collecting the note in year 6.

Taxes when you sell your note

The rule. Selling an installment obligation is a disposition. Gain or loss equals the amount realized minus your basis in the obligation, and it "shall be considered as resulting from the sale or exchange of the property in respect of which the installment obligation was received" (§453B(a)). So capital gain property gives capital gain, and ordinary recapture property gives ordinary income.

Your basis in the note is the face value minus the income you would report if it were paid in full (§453B(b)). IRS Pub. 537 puts it as: multiply the unpaid balance by your gross profit percentage and subtract that from the unpaid balance.

Continuing the example, with a 60% gross profit percentage (see gross profit percentage):

Line Amount
Price received $231,779
Basis in the note ($300,000 x 40%) $120,000
Gain on the sale of the note $111,779
Deferred gain you would have reported if paid in full $180,000

The discount reduces your gain dollar for dollar, from $180,000 to $111,779, but you also receive $68,221 less cash. Assuming married filing jointly with $100,000 of other taxable income, 2026 federal tax on the $111,779 long-term gain is about $16,767 (computed with the §1(h)(1) ordering; state tax excluded). All of it is due for the year of the sale, so plan estimated payments.

Interest. Any accrued but unpaid interest you are paid for is ordinary interest income, not part of the note gain.

Can the sale produce a loss? Only if the price is below your basis in the note, which requires a very deep discount. The loss would take the character of the original sale.

California and other states. State tax on the note gain generally follows the state that taxed the original sale. For a California property sold on installments, California continues to tax the gain even after you move (FTB Pub. 1100).

Borrowing against the note instead

Some sellers pledge the note as collateral for a loan instead of selling it. For taxes, that often does not help: if the original sales price was over $150,000, the net loan proceeds secured by the note are treated as a payment received (§453A(d)), which triggers gain up to the loan amount. Farm property and personal-use property sold by an individual are exempt. See the §453A pledge rule.

Arrangements marketed as a way to get cash from a sale while deferring tax through a separate loan are covered in monetized installment sale. The IRS has proposed treating those as listed transactions.

How to prepare your note for sale

  1. Find the signed original note and the recorded deed of trust or mortgage.
  2. Pull a payment history showing every payment date and amount; a servicer's ledger is best.
  3. Gather the closing statement, title policy and insurance declarations naming you as mortgagee or loss payee.
  4. Confirm property taxes are current.
  5. Know your numbers: unpaid balance, rate, payments left, and your basis in the note from your CPA.
  6. Request written quotes from several buyers, and compare net proceeds after fees and conditions.
  7. At closing, you endorse the note to the buyer and sign a recorded assignment of the deed of trust or mortgage. Notify the payer of the new payment address.

Bottom line

Selling a promissory note turns a stream of payments into cash now, at a discount set by the buyer's required yield and the note's risk. For taxes, it is a §453B disposition: you report the price minus your basis in the note, in the year of sale, with the same character as the original gain. Compare a full sale, a partial sale and a buyer refinance before deciding, and have your CPA run the tax on each.
