As a point for conversation, why does it have to cash flow? If you're looking to build wealth, it's all about cash flow and/or equity. Let's say I purchase a place and it doesn't cash flow at all. But with every mortgage payment, you're building equity. Does that not grow your wealth? How about a property that you paid cash for and are generating net positive cash which is also growing your wealth. Why the cash flow standard? Both scenarios generate wealth. And isn't that the end goal? I'm all for cash flow by the way, but some markets make it hard to find positive cash flow properties.
Just something to think about. I'm personally thinking this through. Generating positive cash flow is desirable, but isn't it really about building wealth? Just my 2 cents.
