What Are Mortgage Notes?

Two Documents, One Deal

Every mortgage loan creates two legal documents. Understanding the relationship between them is the foundation of everything in this business.

The promissory note is the borrower's written promise to repay the debt. It defines the loan amount, interest rate, payment schedule, and maturity date. It is a financial instrument — a piece of paper worth money.

The deed of trust (or mortgage, depending on the state) is the security instrument. It pledges the property as collateral for the debt. If the borrower stops paying, this document gives the lender the legal right to foreclose.

The note is the debt. The deed of trust is the enforcement mechanism. You need both. A note without a security instrument is an unsecured promise — harder to collect, no property backing it up. A deed of trust without a note secures nothing.

When you "buy a mortgage note," you are purchasing the promissory note (endorsed to you) and receiving an assignment of the deed of trust. You step into the lender's shoes — the borrower now owes you. You are the bank.

Whole Loans vs. Mortgage-Backed Securities

There are two ways to invest in mortgage debt.

A whole loan is a single mortgage — one borrower, one property, one debt. You own the actual loan. You control the workout: modify, foreclose, accept a payoff. Every decision is yours.

A mortgage-backed security (MBS) is a bond backed by a pool of thousands of loans. You own a slice of the pool's cash flows, not any individual loan. You have no control over workouts or borrower interactions. MBS trade on bond markets and are priced by Wall Street.

This program — and FIXnotes — deals exclusively in whole loans. When you buy a whole loan, you become the lender with direct control over the asset and every resolution decision.

Performing vs. Non-Performing

A performing loan is one where the borrower is making payments as agreed — ideally on autopay (ACH). These are priced based on yield: a predictable cash flow stream with low risk commands a lower yield (higher price).

A re-performing loan (RPL) is a former NPL where payments have resumed, usually through a loan modification. RPLs are also priced on yield, but at a higher yield (lower price) than clean performers — the borrower has a history of default, so re-default risk is real.

A non-performing loan (NPL) is one where the borrower has stopped paying — typically 90+ days delinquent. No payments are coming in, and the lender is carrying a dead asset on their books. NPLs are priced as a percentage of UPB, not on yield, because there is no cash flow. The percentage varies based on quality — borrower situation, property equity, lien position, state, and resolution probability.

Why Non-Performing Loans Are Investment Opportunities

Banks don't want NPLs. They tie up regulatory capital, drag down performance ratios, and require specialized workout resources most banks don't have. So banks sell them — at steep discounts.

This is the core opportunity: you buy the debt for less than it's worth, then resolve the situation for a profit.

A note with a $100,000 unpaid principal balance (UPB) on a property worth $120,000 might sell for $25,000–$75,000 depending on the borrower situation, property condition, and state. Your job as the investor is to resolve the loan. There are many resolution paths — here are three common examples:

• Loan modification or reinstatement: Restructure the terms so the borrower can afford to pay, or the borrower catches up and reinstates the original terms. You bought the note for $40K, the borrower resumes payments on a modified $80K balance. You earn yield on the cash flow.
• Discounted payoff (DPO) or full payoff: The borrower (or a family member, refinance lender, etc.) pays a lump sum to settle the debt — either at a discount or in full. You bought for $40K, they pay $65K. You profit on the spread.
• Foreclosure or deed-in-lieu: If the borrower won't or can't work with you, you take the property — through foreclosure or a voluntary deed-in-lieu — and sell it. You bought for $40K, acquire the property, and sell for $100K (minus costs).

Each path has different timelines, costs, and risk profiles. You'll learn the full resolution toolkit in Module 6. For now, understand that the discount you buy at creates margin for multiple outcomes.

Key Terms You'll Use Throughout

These terms come up in every deal, every data tape, every conversation in this business:

Every term maps to a number on a data tape and a decision you'll make as an investor.
