Alternatives to HELOC for pulling cash out of primary?

[John M.]

So, I bought a new primary residence a year and a half ago with cash. I'd like to take out a LOC on it to use for fix & flips and/or buy & hold acquisitions. Problem is, I don't have any W2 income since I don't have to work & I prefer to spend my days with my two young children. My wife's W2 income is insufficient & the banks won't consider the capital gains & other variable investment income that covers most of our living expenses, so the DTI kills the loan:

Bank: "So, how do you plan to make the payments on this LOC?"

Me: "With the income I'll generate using the money you lend to me."

Bank: "Take a hike."

Of course the same issue applies to a cash-out refi. Are there any other options for borrowing money against our home? We have great credit and good positive net worth...
