Cost of running an LLC in NC

[Gabe C.]

I'm considering setting up a checkbook LLC IRA with some old IRA money I have from old jobs in order to do a few buy and hold deals with non-recourse loans. I would set up the LLC in NC, and it seems like the setup fee is in the $125 range. My question is what are the costs of running an LLC in NC on an annual basis? Are there yearly fees? Do you pay for a separate tax return to get your K-1 or is it different if it's part of an IRA?

If the fees are prohibitively high in NC for some reason (they are in CA!), my alternative is to just do a regular SDIRA, and bone up on note investing to keep it simple.
