If your goal is to make more cash fairly quickly, but you do not have any substantial personal savings (or don't want to risk it yet), then look at wholesaling or getting your RE license.

To further that mission, we've managed P&L as a portfolio (vs. individual properties), consistently investing in substantial, necessary and voluntary enhancements over decades: new sewer systems, new HVAC, improving drainage, upgrading appliances, adding new porches, etc.  

Once you fully outsource your business (not completely because you'll still be involved to ensure it's still running effectivly) I would say that's the next best thing to passive cash flow.This monthly income derived from wholesaling (which I would imagine would be substantial) will open your investment gates.
