How much do you put down to be cash flow positive?

[Bibi Mathew]

I have people tell me to send them investment properties that are good for rentals all the time when I am at Open Houses. I am in Orange County, California. I understand lot of investors are looking for cash flow positive properties, but in general, with how much down payment is that based on? Because, you put enough down and at one point you're in the positive.
