Yield

Yield is the broadest measure of what a mortgage note investment actually earns for the investor, expressed as an annualized percentage. Unlike the note's stated interest rate (the coupon rate), which reflects what the borrower contractually owes, yield reflects what the investor receives relative to the price paid. Buying a note at a discount to its unpaid principal balance (UPB) increases yield above the coupon rate; paying a premium reduces it. In secondary market note investing, yield is the common language for comparing opportunities across different note types, lien positions, and risk profiles.

Yield vs. Coupon Rate

The distinction between yield and coupon rate is fundamental:

A note with a 7% coupon rate purchased at 85 cents on the dollar will yield more than 7%, because the investor receives full principal repayment ($100,000) on an $85,000 investment while also collecting 7% interest along the way. The exact yield depends on which metric is used and how long the investor holds the note.

Types of Yield in Note Investing

Different yield metrics serve different purposes:

• Current yield — The simplest calculation: annual interest income divided by the purchase price. It ignores principal repayment, the purchase discount, and the time horizon. Useful for a quick snapshot of cash flow relative to capital deployed, but it does not capture the full picture.
• Yield to maturity (YTM) — Accounts for the purchase discount, all scheduled interest payments, return of principal, and the time value of money. Assumes every payment is received on time through the final scheduled payment. Most useful for evaluating performing notes expected to pay through to maturity.
• IRR (Internal Rate of Return) — The most comprehensive yield metric. It accounts for the actual timing of all cash flows, including irregular payments, lump-sum payoffs, or proceeds from a foreclosure sale. Most useful for non-performing notes where the cash flow pattern is uncertain or uneven.
• Cash-on-cash return — Annual cash received divided by total cash invested (including acquisition costs, legal fees, and servicer advances). Not a true yield metric in the financial sense, but widely used by note investors because it reflects real-world returns after all expenses.

What Drives Yield in the Secondary Market

Several factors determine the yield an investor can achieve:

• Purchase price relative to UPB — The deeper the discount, the higher the potential yield. Non-performing loans purchased at 30-50 cents on the dollar target higher yields than performing notes bought at 85-95 cents.
• Note interest rate — A higher coupon rate produces more interest income per dollar of UPB, directly increasing yield.
• Remaining term — Shorter remaining terms accelerate the return of the purchase discount through principal payments, boosting yield. Longer terms spread the discount over more time.
• Prepayment speed — If the borrower pays off early through refinance or property sale, the investor receives the full UPB sooner, increasing annualized yield on a discounted note. This is why prepayment penalties are less common in the note-buying world — early payoff is usually welcome.
• Resolution outcome (NPLs) — For non-performing notes, yield depends entirely on the workout strategy: a successful loan modification that re-performs, a discounted payoff, or foreclosure and REO sale each produce different return profiles.

Practical Application

When evaluating a note for purchase, experienced investors typically model yield under multiple scenarios: a base case (expected outcome), an upside case (early payoff or favorable resolution), and a downside case (extended default, foreclosure, below-expected recovery). Comparing the probability-weighted yield across scenarios gives a more realistic picture than any single number. The target yield should compensate for the risk profile — first-lien performing notes at 8-12%, junior liens at 12-18%, and non-performing notes at 15-25% or higher are common benchmarks, though actual returns vary with market conditions and individual deal quality.
