Why I Rejected a Deal at 10% Down (Even Though It Almost Broke Even)
A deal that almost cash flows is, in practical terms, a deal that does not work. I walk through a real example — the same property, three financing structures — and explain why 'close' isn't good enough.
In real estate investing, "almost" is a word that deserves scrutiny. A deal that almost cash flows, almost covers its debt service, or almost meets your return threshold is, in practical terms, a deal that does not work. This distinction is not a matter of semantics. It is the difference between a sustainable investment and a liability that quietly erodes capital month after month.
I want to walk through a real example that illustrates this principle clearly: a property that, depending on how it was financed, could be a clear rejection, a marginal maybe, or a solid addition to a portfolio. The property itself never changes. Only the financing structure does.
The Property
Consider a $400,000 property generating $3,000 per month in rent, or $36,000 annually. After accounting for $10,400 in annual operating expenses — taxes, insurance, maintenance, management, and vacancy reserves — the property produces $25,600 in Net Operating Income (NOI).
Financed at a 6% interest rate on a 30-year term, the outcomes across three down payment structures are stark. At 0% down, the deal loses $3,200 annually. At 10% down, it loses $320. At 25% down, it generates $4,000 in annual cash flow — a 4% cash-on-cash return on a $100,000 investment.
Same property. Same rent. Same expenses. Three completely different outcomes based entirely on leverage.
Reading the Numbers
At 0% down, the deal is straightforward to evaluate: it loses $3,200 annually. Full leverage does not compensate for a structure that fails to cover its own obligations. This scenario is rejected without much deliberation.
At 25% down, the deal works cleanly. It produces $4,000 in annual cash flow — conservative, self-sustaining, and durable across a range of market conditions.
At 10% down, the deal sits in a more difficult category. The annual cash flow is –$320, which is close enough to zero that it may be tempting to round up and call it acceptable, particularly if the alternative is losing the deal to another buyer. I do not make that adjustment. A property that requires $40,000 in capital and still fails to produce positive income does not meet the standard I apply before committing to a purchase.
Why "Close" Isn't Good Enough
There are three reasons I hold this line, even when a deal is only marginally negative.
First, conservative projections already build in a margin of safety. My NOI assumptions typically account for vacancy, repairs, and expense increases in a deliberately cautious way. If a property is negative even under these assumptions, actual performance is unlikely to be more favorable. The math is telling me something before the market does.
Second, a break-even or negative property still carries opportunity cost. Forty thousand dollars committed to a property producing –$320 annually is $40,000 not available for a different property structured to produce $4,000 or more. Capital that is tied up and underperforming is capital that cannot be redeployed.
Third, and most importantly, income should determine the debt, not the reverse. If a deal only works by accepting a negative or marginal cash flow, the correct response is not to accept the loss — it is to restructure the financing, negotiate the purchase price, or decline the deal.
The Broader Principle
Leverage amplifies outcomes in both directions. Additional debt increases the potential upside of a deal, but it also increases the downside risk when income does not fully support the payment. A financing structure that produces a small loss is not a smaller version of a good deal. It is a different deal entirely — one that fails the primary test before any other factor is considered.
I would rather pass on ten deals that are close than accept one that requires me to make an exception to my own standards. Consistency in underwriting, applied deal after deal, is what protects a portfolio over the long term.
