How can equity to get more cash flow?

[Ilya Z.]

How can you invest equity in existing free and clear rentals long-term to get more cash flow? Seems like today's cash-out rates are too high to get positive flow if you buy a turnkey rental, since rents where I've looked are below 1%. You can get a HELOC against it and use it for BRRR rehabs. But it's short-term and may or may not be better that getting hard money. Any other options? Any of those options more passive than investing in residential rentals? TIA!
