How to Price Real Estate Notes Using Cash-on-Cash Return

Why Cash-on-Cash Return Is the Starting Point for Pricing Notes

When a seller hands you a tape of performing loans or re-performing loans, the first question is always the same: what should I pay? Unlike non-performing loans — where pricing is driven by property value and projected resolution outcomes — cash-flowing notes already generate predictable monthly income. That income stream is the basis of your valuation.

Cash-on-cash return is the simplest and most widely used metric for pricing notes that are already paying. It measures the annual net income you receive from a loan divided by the amount of capital you invested to acquire it. The formula gives you a direct answer to the question every investor asks before writing a check: "If I pay this price, what percentage return will my money earn each year?"

This approach works for first-lien and second-lien performing notes, re-performing loans that have been modified and are making consistent payments, and any other note where a borrower is actively sending monthly checks. It is the same logic that drives pricing in the broader cash-flow investment world — rental properties, dividend stocks, annuities — applied specifically to mortgage notes.

The Cash-on-Cash Formula for Mortgage Notes

The formula has three inputs:

1. Monthly payment (P&I). This is the contractual monthly principal and interest payment the borrower is making. You find this on the seller's data tape, typically in a column labeled "monthly payment" or "P&I payment."

2. Monthly servicing fee. Every loan requires a loan servicer to collect payments, manage escrow, send statements, and handle compliance. The servicer charges a monthly fee — typically $15 to $30 per loan for performing notes. This fee comes directly out of your cash flow and must be subtracted before calculating your return.

3. Target cash-on-cash return. This is the minimum annual yield you require on your invested capital. The target you choose depends on your risk tolerance, your cost of capital, and the quality of the loan. Higher-risk notes (seconds, recently modified loans, borrowers with weaker credit) demand higher target returns. Lower-risk notes (firsts with strong equity, seasoned performers) can justify lower targets.

The formula:

Maximum Purchase Price = ((Monthly Payment - Servicing Fee) x 12) / Target Cash-on-Cash Return

This formula works in reverse from most return calculations. Instead of knowing the price and solving for the return, you set the return you want and solve for the maximum price you can afford to pay.

Worked Example: Pricing a Re-Performing Loan

Consider a re-performing first-lien mortgage with the following characteristics from the seller's tape:

Now price this loan at two different target returns:

At a 12% target return, you would pay $66,100 for this loan — roughly 76% of the unpaid principal balance. At a 16% target, the price drops to $49,575, or about 57% of UPB. The math is straightforward, and it scales to any loan on the tape.

The percentage of UPB that these prices represent is a useful sanity check. If your cash-on-cash formula produces a price above 100% of UPB, you are overpaying — no loan should cost more than the remaining balance owed. If the price falls well below typical market ranges for the asset class, your target return may be unrealistically high for the quality of the loan, and your bids will not be competitive.

Capping Your Bid at UPB

One important guardrail: no matter how attractive the cash-on-cash return looks, you should never pay more than the unpaid principal balance. The UPB represents the maximum amount the borrower owes. If you pay more than UPB, there is no mathematical path to recovering your full investment through the loan's contractual payments alone — you would need the borrower to pay beyond their legal obligation, which will not happen.

In a pricing spreadsheet, this cap is implemented with a simple MIN formula:

Final Bid = MIN(Cash-on-Cash Price, UPB)

This matters most on smaller-balance loans with high interest rates. A loan with a $15,000 UPB and a $250 monthly payment produces $2,760 in annual net income after servicing. At a 12% target return, the cash-on-cash formula suggests paying $23,000 — well above the $15,000 owed. Without the UPB cap, you would overpay by $8,000.

Loan B and Loan D illustrate why the UPB cap matters. Without it, you would bid more than the borrower owes.

Choosing Your Target Return

The target cash-on-cash return you select depends on the risk profile of the note and the competitive landscape of the market. Different asset classes in the secondary mortgage market trade at different yield expectations:

These ranges are not fixed. They shift with market conditions, interest rate environments, and the volume of supply and demand in the secondary market. However, they provide a useful framework for setting your target return before you start pricing a tape.

A common mistake among newer investors is setting a target return that is too aggressive for the asset class. If you price every performing first lien at a 20% cash-on-cash target, your bids will consistently fall below market and you will never win an allocation. Conversely, if you price risky re-performing seconds at 8%, you are not being compensated for the additional risk of subordination and reperformance failure.

Cash-on-Cash vs. Internal Rate of Return

Cash-on-cash return is a powerful screening tool, but it has a significant limitation: it does not account for how long you will earn that return. A note that pays 12% cash-on-cash for 25 years is a fundamentally different investment than one that pays 12% for 18 months before the borrower pays off the loan in full.

Consider two scenarios for the same $66,100 note:

In the early payoff scenario, you receive your full purchase price back (since the borrower pays the remaining UPB) plus six months of income, which produces a much higher annualized return on investment than the stated 12% cash-on-cash. This is why experienced note investors also calculate the internal rate of return (IRR) — it factors in the time value of money and the total cash flows over the life of the investment, including the return of principal at payoff.

The practical takeaway: use cash-on-cash return to set your purchase price and screen deals quickly. Then run an IRR calculation to model different payoff scenarios and ensure your longer-term yield still meets your requirements.

Building a Pricing Spreadsheet

The power of cash-on-cash pricing is that it scales. When a seller sends you a tape with 50 or 100 performing loans, you do not need to build a custom financial model for each one. A single spreadsheet with standardized columns will price the entire tape in minutes.

At minimum, include these columns:

You can add as many target return columns as you want. Running the tape at 12%, 14%, 16%, and 18% simultaneously lets you see how price sensitivity changes across yield expectations and helps you determine where in the range each loan falls.

For a re-performing trade, you may also want to add columns for the borrower's payment history since modification, the original delinquency status, occupancy, and any other data points the seller provides. These qualitative factors help you decide which target return to apply to each individual loan — a re-performing note with 12 months of on-time payments deserves a lower yield target (and therefore a higher price) than one with only 3 months of history.

Common Pricing Mistakes

Forgetting to subtract the servicing fee. The monthly payment on the tape is the gross amount the borrower pays. Your actual cash flow is that payment minus the servicer's fee. On a $300 monthly payment, a $20 servicing fee reduces your annual income by $240 — which changes your price by $2,000 or more depending on your target return.

Ignoring the UPB cap. On high-coupon, low-balance loans, the cash-on-cash formula can produce prices that exceed the amount owed. Always apply a MIN function or manual cap to ensure your bid does not exceed UPB.

Using a single target return for all loans. Not all performing notes carry the same risk. A first lien behind an owner-occupied property with 50% equity is not the same as a recently modified second lien behind a non-owner-occupied property with minimal equity. Adjust your target return to reflect the risk profile of each loan.

Treating cash-on-cash as the only metric. Cash-on-cash return is a snapshot of year-one income relative to your investment. It does not capture prepayment risk, default risk, or the time value of money across the full life of the loan. Always supplement with an IRR analysis for any loan you are seriously considering.

From Pricing to Offer

Once you have priced every loan on the tape, your spreadsheet becomes the basis for your letter of intent (LOI). Sum your individual bid prices across all the loans you want to purchase, and that total becomes your offer to the seller.

Sellers of performing and re-performing notes evaluate bids differently than NPL sellers. With cash-flowing assets, the seller often has their own yield expectations and will compare your bid to the cash flow the loan is generating for them. If your offer implies a yield that is significantly above the seller's current return, they have less incentive to sell — they are already earning a good return by holding. The best opportunities come when sellers have a motivation beyond yield: portfolio rebalancing, regulatory pressure, capital redeployment, or fund liquidation timelines.

The discipline of cash-on-cash pricing keeps your bids anchored to fundamentals. You know exactly what return you will earn at any given price, and you can walk away from any tape where the seller's expectations exceed what the cash flow supports. That discipline — not deal volume — is what protects your capital over the long term.
