Cash Flow Investing: The Investor's Playbook

How to identify, underwrite, and operate properties that produce reliable monthly cash flow.

Defining Real Cash Flow

True cash flow is what hits your bank account after every expense — including reserves for vacancy, maintenance, capital expenditures, and management. Many novice investors calculate 'cash flow' as rent minus mortgage, which dramatically overstates returns.

The 1% Rule and Why It Matters Less Today

The classic 1% rule (monthly rent ≥ 1% of purchase price) is rarely achievable in major U.S. metros today. It remains useful as a screening shortcut, but most modern cash-flow investors focus on cash-on-cash return targets of 8–12%.

Building a Reserve Stack

Plan for vacancy at 5–8%, maintenance at 5–10% of rent, capex at 5–10% of rent, and management at 8–10% of rent. Properties that cash-flow only because the owner self-manages and self-repairs are not truly cash-flowing.
