How the Secondary Market Works

The Life Cycle of a Loan

To understand where your investment opportunities come from, follow the life of a loan:

This is the secondary mortgage market — where loans trade after origination. And it's where you operate as a note investor.

Why Banks Sell

Banks sell NPLs for three interconnected reasons:

Regulatory capital requirements. Banks must hold capital reserves against non-performing assets. Every NPL on the books locks up capital that could otherwise be deployed into new, performing loans. Selling NPLs frees that capital.

Non-performing asset ratios. Regulators track the percentage of a bank's portfolio that is non-performing. A high ratio triggers increased scrutiny, potential restrictions, and reputational damage. Selling NPLs improves the ratio immediately.

Risk transfer. Working out a delinquent loan requires specialized staff, legal resources, and time. Most community banks and credit unions don't have dedicated workout teams. Selling transfers the workout risk and cost to a buyer who specializes in it.

The result: banks are motivated sellers. They accept significant discounts on UPB because the alternative — holding, servicing, and eventually foreclosing — is more expensive and slower.

Charge-Offs and Non-Accrual

Before selling an NPL, the bank typically charges off the loan — an accounting action that writes the asset down to its estimated recoverable value. This doesn't forgive the debt. The borrower still owes. But the bank has acknowledged the loss on its books.

After charge-off, the loan is classified as non-accrual — the bank stops accruing interest. No new interest is added to the balance. The loan sits as a charged-off asset until the bank sells or resolves it.

Most NPLs that reach the secondary market are post-charge-off. Media sometimes calls this "zombie debt" — old obligations that resurface when a new creditor buys them. That framing assumes bad faith. When the new lender doesn't retroactively charge years of past-due interest, offers reasonable workout terms, and treats the borrower fairly — these are simply loans that need resolution. The borrower still lives in the home. There's still a lien on their house. A fair workout benefits everyone.

As a note investor buying post-charge-off loans, the balance you work with is the UPB at charge-off. You are not stacking accrued interest on top. This is one reason workouts succeed — borrowers engage when the numbers are fair.

The Players

The secondary market has a clear structure. Know who does what:

Sellers — banks, credit unions, and mortgage companies that originated or acquired loans and now want to sell the non-performing ones. Some large banks sell quarterly in bulk; smaller banks sell ad hoc when portfolios accumulate enough NPLs.

Aggregators and hedge funds — large-scale buyers who purchase pools of hundreds or thousands of loans directly from banks. They cherry-pick the best assets for their own portfolios and re-sell the rest in smaller pools to downstream buyers. They're the wholesalers of the market.

Brokers — matchmakers who connect sellers with buyers. They don't take ownership of the notes. They earn an assignment fee or commission for facilitating the transaction. Broker quality varies widely — some add real value through relationships and deal flow, others just forward tapes.

Marketplaces — platforms (like FIXnotes) that aggregate inventory from multiple sellers and provide a structured buying process. They streamline what would otherwise be a relationship-driven, opaque market.

Individual investors — that's you. Buying one to ten notes at a time, running due diligence, and resolving loans for profit. You'll buy from aggregators, brokers, marketplaces, and occasionally directly from small banks.

How Loans Are Packaged and Sold

Loans are sold as pools — groups of loans bundled together. The seller provides a data tape — a spreadsheet with loan-level details: UPB, interest rate, property address, borrower payment history, lien position, property type, and more.

As a buyer, you review the tape, filter for assets that match your criteria, and submit bids on the ones you want. You'll learn how to read and filter tapes in Module 2.

Pool sizes vary by seller:

• Institutions sell pools of hundreds to thousands of loans
• Aggregators re-sell in pools of 10–100
• Marketplaces and brokers often sell individual notes or small pools of 1–10

What "Qualified Buyer" Means

Sellers don't sell to just anyone. To buy mortgage notes, you typically need:

• A legal entity (LLC or similar) — sellers won't transact with individuals
• Proof of funds — evidence you can close (bank statement, SDIRA balance, or lender commitment letter)
• Vetting and compliance — many sellers require background checks, compliance attestations, and proof you understand servicing obligations

This isn't gatekeeping for its own sake. Sellers need to know that their loans will be serviced legally and that borrower protections will be maintained. Module 7 walks you through building your vetting package.

How Pricing Works

Performing loans and RPLs produce cash flow, so they are priced based on yield — the return on the payment stream. A clean performer on ACH with no default history might trade at 8–9% yield. An RPL with re-default risk trades at higher yields — typically 10–15% cash-on-cash returns — to compensate for the uncertainty.

NPLs are different — there's no cash flow, so pricing is expressed as a percentage of UPB. A bid of "35 cents on the dollar" on a $100,000 UPB note means you're offering $35,000.

What Drives NPL Pricing

Every factor that affects resolution probability affects price:

Typical Ranges

The wide NPL range reflects the diversity of situations. A first lien with deep equity and an engaged borrower trades near the top. A second lien on a vacant property with delinquent taxes trades near the bottom. You'll learn how to price assets precisely in Module 3.
