Joel,
This is a topic that really can't be adequately covered here, but I'll share some perspectives with you anyway. If I'm understanding what you said correctly, and if I'm reading between the lines correctly too, I think I understand what you want. But, I don't think you're going to be able to use your LLC and/or a Line Of Credit (LOC) as you described to accomplish your desired goals, AND I don't think you're going to be at all happy with the options Greg listed either due to the lousy (my opinion) loan terms involved. However, I'm confident that you CAN get to where you want to be.
With that said, if you are comfortable with rates possibly adjusting on you, 3 to 5 year calls, etc., then go for it. Just go into it with your eyes WIDE OPEN and start trying to improve your positions right from the very beginning.
I use LOCs heavily in my Real Estate Investing business, and I always have. I think they're absolutely beautiful! BUT, I wouldn't want to use one for a long term loan due to the fact that LOC interest rates can increase at basically any time. I'm also a big boy and know better than to run to Vegas with the money :-) Depending on your situation (i. e. credit score, Debt-To-Income ratio (DTI), job stability, assets, etc.), I can refer you to some of the lenders and LOC types we've gotten over the years along with what works and doesn't work in the application process.
I could go on and on about how we also use conventional loans, private money, etc., but here's one last point for now. There's plenty of money out there just waiting to find your great deals. Find the deals, network with other investors, and the funding will almost track YOU down.
If you'd like to hear a lot more details on how my wife, Cindy, and I have financed our deals, our overall funding plan, and other resources, please feel free to give me a call at 817-300-1132.
Thanks,
Robin
