How the Math Works
NOI = Rent × (1 − vacancy%) − operating expenses
Cash-on-cash = Annual cash flow ÷ Cash invested
Worked example: $250,000 property, 25% down ($62,500 + $5,000 closing = $67,500 invested). Loan: $187,500 at 7.0%/30yr = $1,248/month debt service. Rent $1,900 with 6% vacancy ($114) and $500/month operating costs → NOI ≈ $1,286/month. Cash flow = 1,286 − 1,248 = +$38/month — break-even. Cash-on-cash = $456 ÷ $67,500 = 0.7%. At 2026 rates, this is the honest math most gurus skip: positive cash flow at 25% down is rare; the same deal at 40% down ($112,500 invested, $1,065 payment) cash-flows +$221/month = 2.4% cash-on-cash plus amortization plus appreciation. Total return = cash flow + principal paydown (~$9,600/yr early on here) + appreciation; see our rental yield calculator for the unleveraged view.
Cash Flow FAQ
What is a good cash-on-cash return?
Benchmark against alternatives: risk-free treasuries set the floor. Many experienced investors want 6-8%+ cash-on-cash plus appreciation; at 2026 interest rates, 3-5% with strong appreciation markets is common and defensible.
Why is my cash flow negative at 20% down?
Because 7% mortgage rates exceed the cap rates of most residential property. Fixes: bigger down payment, buy below market, increase rent responsibly, or accept negative cash flow as the price of appreciation bets — knowingly.
What is the 50% rule?
A planning shortcut: expect operating expenses (including vacancy and taxes) to consume ~50% of gross rent. If rent is $1,900, expect ~$950 for everything except the mortgage. Reality varies 35-60%.
Does appreciation count in cash flow?
No - cash flow is what hits your bank account monthly. Appreciation and principal paydown are separate return components; the IRR guide on this site combines all three.
