You may be able to get creative with Mezzanine debt or Preferred Equity, but those are typically for larger short term deals. 

I did a little research already and found the following:It is not required in every case for you to have a true debtor-creditor relationship with your lender to take the mortgage interest deduction.

Is the LLC going to be getting the loans or debt or will you still carry it in your personal name?

📈 Preferred equity (PE) is the layer of a capital stack that sits in between common equity and the senior debt (or sometimes Mezz).Since we always read the capital stack from the bottom up, we can see that senior debt is always paid first, then preferred equity, and then finally common equity.Often PE investors are providing a large chunk of equity, and therefore, want to get paid first (preferred position) before the common equity.By getting paid first, the PE provider is in a less risky position compared to the common equity investors.✔️ Important: PE is interesting because it has characteristics of both debt and equity.

No "significant" need for more "equity investing," time for debt or income investing. 

The question is do you have a clear path for that money, the discipline to use it only for assets that will produce an income to pay off that debt or service the monthly payment.

Are your funds using agency debt or are their loans callable and /or expire after a few years?

@Dane O StewartAs @Chris Seveney as leading towards, are these investor(s) lending you money (e.g. debt or debt stack) taking equity (e.g. ownership) in the deal. 

Regardless, good debt or bad debt is the same in regards to how you have to pay it.

In the example above that would be $100K*80%= $80KYou can apply for a HELOC at 80%, use that money and pay off the credit card debt or at least most of it.Important final point, and I think that is what Caleb and Charles are pointing towards: Ask yourself if that balance on the credit card is a result of spending you had to make at that point in time (i.e. emergency) and with a frugal/practical mindset, or was there spending that as frivolous.You might say: "it was a little bit of both".
