How can I speed up my acquisition of properties?

I'm a new investor and, right now, I don't have any money (<10k). But I'm planning to purchase my first quadplex by the end of this year. After I purchase this first property through my VA loan, I'd like to initiate a sort of rapid acquisition phase where I'm purchasing a quadplex 6 months after the first purchase.

I need some financing ideas/tips: how can I fund this rapid acquisition plan? To those who purchase more than one property per year, how do you do it?

PMs are open if that's preferred!

Thank you!
