Go with SDIRA LLC but large upfront cost will eat either nest egg/emergency fund/or cc charge. 

I'm not a business owner, but I feel like $24000 in CC debt is a lot for a small business to have.

I've tried more than once to get CC officers to give me vendor referrals with no success.  

This roofing company does not (they actually charge more if you use a credit card to pay instead of cash/check to cover the CC processing fees). 

If you are hiring out the work, you can probably find a CC with zero interest for 12 months and only 3-5% draw fee.

I use my 2% CC always for supplies too.

Quote from @Brian C.: Hi FrankTurnkey out of state?

Now if you could get a loan for the credit card amount at a lower interest rate then ya, but getting more debt on a gamble to maybe save 100-200/month to pay off your insane interest rate CC doesn't seem like something i could ever do.Granted everyone has their own situation and not any situation is the same but based off what you have said soo far, even paying your credit down now, you are not sure how long your single income is going to last for so you will probably be using that Credit card and accumulating more debt.

Also, if you are projecting a 20% C/C that means the rehab must cost less than 21K to break even ($350*12)/.20.I would price based on existing cash flow and check that against recent sales. 4 units are appraised based on comparable properties, not cash flow, so run both analysis.If it's an older building with deferred maintenance, then consider raising CAPex to 10%Also, your existing expenses are missing, you just have CAPex, Vacancy and PM set aside going forward.

The only CC left to pay off is my Amazon CC, which should get paid off next paycheck.
