How easy would it be for me to use HELOC to fund my RE investments after I decide to buy my primary home in San Jose, CA?

They are saying I will need to co-sign, however, I was planning on signing on a new HELOC under my name on another property in the next day or two.  

Larger HELOC in one property and refinancing another.  

@James Black doing the refi might stop your cash flow , another option is Heloc if you have equity on your primary residence.

Specifically if I were to borrow from a family member’s HELOC how would the actual transaction of money transfer work?

Approximately $5k out of profits from other rentals cashflow and the remaining down payment with a HELOC.

After you have established some equity, get a home equity line of credit (HELOC) and use that for your investing.

We have a decent amount of equity in our primary home so I'm hoping to secure a HELOC, then possibly Flip my first investment to build the capital needed for a Rental property.

@Russ Marlborough Do you have equity in another property that you can do a HELOC on?

Purchase price: $83,300 Cash invested: $17,000 This was my first BRRR and I used all the strategies that BP has suggested.Started up by opening a HELOC on my primary to have 100K of cash at hand.
