ISO means to leverage equity in rental property for flips

[Kim Thomas]

I own a condo in Hall County, GA (near Gwinnett). The mortgage was paid off about 5 years ago and owe $2600 on a HELOC that's in the repayment phase.
Market value is $200k.

I flip residential properties in NC. Rather than having to pay $10k in closing costs to my HML for every house I buy, I'd like to use the equity in this rental to purchase.

Because I'm usually in and out of a house in 3 to 6 months a cash out refi or DSCR won't serve my needs.

I've spent hours (totaling weeks) looking for a HELOC (I've called every credit union and small to mid bank in the area, PenFed, contacted a host of online lenders and brokers both in the area and across the US). No dice.

How else can I use $150k (75%) of equity in this rental on a repeat basis?
