A private mortgage note trades at a price set by four things: how the borrower has paid, how much equity stands behind the lien, how clean the file looks to a buyer’s due-diligence reviewer, and the buyer’s required yield on capital at the moment of trade. The first three sit inside the seller’s control. The fourth moves with rates, credit appetite, and capital flows in the private-credit market — a market the AAPL/Lightning Docs Origination Report sized at roughly $49B of annual private-lender originations and a wider $2T residential note universe by face value. This guide walks the pricing math, the due-diligence packet, the federal rules that govern the transfer, and the servicing discipline that turns a thin note into a premium-priced trade.

Why does servicing history drive note price?

A buyer pricing a performing private note discounts every uncertainty about future cashflow. Twelve months of clean payment history removes most of that uncertainty. Two missed payments inside a twenty-four-month window adds it back. The servicing record is the artifact that demonstrates which of those two stories is true. A complete record shows date, amount, source, and method for every payment received; every escrow disbursement; every borrower communication; every notice mailed or emailed. A buyer that trusts the record will pay a tighter spread because the buyer no longer has to underwrite the missing pieces. A buyer that does not trust the record either passes or discounts the trade to absorb the risk.

What sets the price of a private note?

Five inputs do most of the work. Each one moves price in a predictable direction; in combination they explain most of the bid spread on a residential mortgage note.

  1. Investment-to-Value (ITV). Purchase price divided by current property value. Lower ITV protects the buyer’s basis if the borrower defaults — the buyer takes the property at a discount to market and recovers principal at sale.
  2. Seasoning and payment history. Number of months the borrower has paid as scheduled. Twelve months of clean pay is the threshold most buyers price as a “seasoned performing” note.
  3. Borrower credit and capacity. Re-pulled FICO at trade, plus debt-to-income and employment verification when available. These are predictors of continued performance.
  4. Collateral quality. Property type, occupancy (owner versus non-owner), lien position, state foreclosure regime, and current valuation method (BPO, drive-by appraisal, full appraisal).
  5. File completeness. Original note, allonges, recorded mortgage or deed of trust, title policy, full payment history, escrow ledger, modification documents (if any), and servicing comments. Missing pieces price as risk.

How do you calculate yield on a note purchase?

The buyer’s yield is the internal rate of return on the future cashflows of the note, given the purchase price. Consider a note with a one-hundred-thousand-dollar unpaid principal balance, a one-thousand-dollar monthly payment, and 240 remaining months. Bought at a meaningful discount to UPB, the note carries a yield well above the note’s coupon rate — the discount to face is the yield uplift. The math runs in any financial calculator or spreadsheet: present value (purchase price), payment, term, and solve for rate. The remaining balloon, if any, enters as a future value at the balloon date. The same math runs in reverse: a buyer targeting a specific yield computes the purchase price that produces it. Sellers price against a range of buyer yield targets and choose the trade that maximizes proceeds net of cost.

What is the difference between a whole-note and a partial sale?

A whole-note sale transfers all rights and remedies in the note and mortgage to the buyer for an agreed price. The seller is paid out and the buyer becomes noteholder of record. A partial sale — sometimes called a partial — transfers a defined slice of the cashflow stream (say, the next 60 payments) for an upfront price. The seller retains the tail of the note. Partials let the seller pull cash forward without exiting the position; whole-note sales monetize the full position at one yield. Partials carry more documentation complexity — a servicing agreement, a custody arrangement, sometimes an allonge specifying the assigned interest — but produce a higher blended price when the tail has long-term value.

How do you build a note sale due-diligence packet?

Buyers price a clean file at a tighter spread. The packet that closes at a premium contains, at minimum: the original note with all allonges; the recorded mortgage or deed of trust with all assignments; the title insurance policy and any endorsements; a complete payment history showing date, amount, principal-interest split, escrow allocation, and remaining balance after each payment; the escrow ledger with tax and insurance disbursements; any modification, forbearance, or repayment-plan documents; the borrower’s original signing package; current insurance declarations; the latest tax bill or paid-tax confirmation; and the servicer’s communication log. A packet missing the title policy or recorded security instrument either kills the trade or drops the price by whatever the buyer’s reviewer estimates the curative work will cost.

How does Henson v. Santander shape note buyer compliance?

In Henson v. Santander Consumer USA Inc., 137 S. Ct. 1718 (2017), the Supreme Court read the FDCPA’s “owed or due… another” language to mean exactly that: a party that buys a debt and collects for its own account is not collecting a debt “owed or due… another” and is therefore not a “debt collector” under §1692a(6). The decision matters for note buyers acquiring defaulted or sub-performing paper. The buyer that takes assignment and collects on the buyer’s own account sits outside FDCPA debt-collector obligations on those loans. State debt-collection statutes and other federal rules — RESPA, TILA, FDCPA when the buyer is in fact a “debt collector” under a different prong of §1692a(6) — still apply. Counsel review on classification is non-optional at acquisition.

What does §1024.33 require when servicing transfers?

Regulation X §1024.33 controls notice on transfer of servicing for federally related mortgage loans. The transferor servicer sends the borrower a Notice of Servicing Transfer no fewer than fifteen days before the effective transfer date. The transferee servicer sends its own notice no later than fifteen days after the effective date. The notice carries the effective date, the new servicer’s name and contact information, and the date payments should begin going to the new servicer. The first sixty days after transfer are a §1024.33(c) grace period: a payment received on time at the old servicer’s address cannot be treated as late. A note sale that transfers servicing must run the §1024.33 timing exactly or the buyer inherits a UDAP exposure on day one.

When does a note buyer need a state lender or servicer license?

The licensing answer depends on three things: the state of the property, the state of the borrower’s residence, and the buyer’s role. A pure note buyer that takes assignment and uses a licensed third-party subservicer in compliant states avoids the licensing burden in most jurisdictions. A buyer that self-services or sends borrower-facing collection notices triggers servicer-licensing requirements in states such as California, New York, Maryland, Washington, Texas, and many others. The SAFE Act adds licensed loan-originator requirements when the buyer offers, negotiates, or modifies an owner-occupied consumer loan. Multi-state portfolios sit inside a fifty-state licensing analysis that should be completed before any binding purchase commitment, with qualified counsel on the call.

Expert Take — Why does the servicing record set the price?

“When a buyer’s due-diligence team opens a tape, the first thing they look at is not the borrower and not the property. It is the payment history. A clean, machine-readable record of every payment going back twelve, twenty-four, thirty-six months tells them the note has been managed. The record built by a borrower-volunteered spreadsheet does the opposite — it tells them they will have to rebuild the history themselves before they can underwrite the trade. We have watched the same note get two bids that differed by four hundred basis points on yield, and the only difference was the quality of the servicing record.” — Thomas Standen, President, Note Servicing Center

Frequently Asked Questions

What is the difference between UPB and face value?

Unpaid principal balance (UPB) is the current outstanding principal after the most recent payment. Face value is the original loan amount on the day the note was written. Buyers price against UPB, not face. A $200K original note that has amortized to a lower UPB trades against the current UPB — and the buyer’s yield calculation runs from today’s UPB and the remaining payment stream.

How long does a note sale take to close?

A clean performing-note trade with a complete file closes in two to four weeks from term sheet to funded. A non-performing or sub-performing trade with title curative work or missing collateral extends to six to twelve weeks. The two compression points are the file delivery (front end) and the recorded assignment and allonge (back end). Sellers that pre-build the packet shave a week off both ends.

What is a re-performing loan and how does it price?

A re-performing loan (RPL) is a note that defaulted, cured through workout or catch-up, and has paid as scheduled for a defined seasoning window — six months is the threshold most institutional buyers use. RPLs price below seasoned performing notes (the buyer adds a yield premium for the prior default) and above non-performing notes (the buyer credits the demonstrated cure). The depth and duration of the post-cure history move the price within that range.

Does the borrower have to consent to the note sale?

No. The note and mortgage are negotiable instruments that transfer by endorsement and assignment. The borrower has no consent right unless the loan documents create one — and most standard private mortgage notes do not. The borrower has a right to notice under RESPA §1024.33 (consumer-purpose, federally related loans) and under most state servicer-licensing regimes, and the borrower retains all rights and defenses against the new noteholder that existed against the prior holder.

What is a tape and what should it contain?

A “tape” is the structured-data file a seller sends to prospective buyers describing the notes for sale. A standard tape carries one row per loan with fields covering: loan number, borrower last four digits, property address (anonymized to state-county-zip if pre-trade), property type, occupancy, original face, UPB, coupon rate, original term, remaining term, monthly payment, escrow balance, last paid date, paid-to date, payment history string (twelve to twenty-four months), original LTV, current ITV, BPO or appraised value, lien position, and modification history. The tape is the trade screening tool; the file is the closing tool.

How do you price a non-performing note?

The buyer prices against expected recovery from collateral, not from continued payments. The math: current property value times expected sale percentage (a discount to fair-market value), minus foreclosure cost, minus carrying cost across the state foreclosure timeline, minus the buyer’s required return on capital at risk across the same window. Per ATTOM Q4 2024 data, that window runs 82 days in New Hampshire to 3,038 days in Louisiana, with a national average of 762 days. The buyer that misprices the state timeline misprices the bid.

Expert Take — What buyers really pay for at closing

“What the buyer pays for is not the note. The buyer pays for the certainty that the next payment will arrive on the date the amortization schedule says, that the file in the data room matches the loan that closed, and that the chain of assignments runs unbroken from origination to today. Every dollar above the collateral-recovery floor is a dollar the buyer is paying for that certainty. The seller who controls the servicing record controls the price.” — Thomas Standen, President, Note Servicing Center
