Cash Flow Potential: Rental income from real estate held in an SDIRA flows directly back into the account, allowing you to reinvest and compound your wealth tax-advantaged.

The cash flow over a long hold is tightly coupled to appreciation. 

Negotiating a better interest rate on your refinance would reduce your monthly mortgage payments, helping boost cash flow.

Quote from @Clayton Silva: 2nd position HELOCS on investment properties are typically capped at 70% LTV and have rates ranging from 9-11% just a heads up unless you use a local credit union where you have cash on deposit with them. 

All strategies start with buying 1 property and adding $10k cash every year. 

A majority of people who rent homes here have 100% equity in them so any rent will cash flow. 

You only take what you need when you need it.Heloan usually means 2nd place like a cash out refinance but they do not pay off the first mortgage they give you an amount in cash like the $10K above. 

Using simple numbers, assume I want to purchase a $100,000 property using crypto as collateral:- I pay the closing costs with cash- I put down 10% down payment with cash ($10,000) - I utilize a crypto mortgage for the remaining 90% ($90,000) This way, I still keep my crypto and I have a property, both of which may accrue in value over the long-term.

Access to Cash Value: A properly structured permanent life insurance policy (like an IUL or whole life) can build cash value that you can borrow against for property acquisitions, renovations, or even as a safety net during market downturns. 2.

as mentioned the most common way is you do a cash out refinance to buy an ex out of a property.
