Over time I was able to increase my limits to more business credit card amounts and acquired business credit card debt through investing and payments to  rehabs.My dilemma is that I have a 65K in business credit card debt (between 10% to 17% APR) and 136K in available business credit card available.Should I focus on paying of the remaining business credit debt or invest in another property? 

I may have to re-enlist, but I would like to avoid that if possible.Should I focus on paying down the rest of that debt, or should I switch gears to saving up for a down payment on the investment property once the first three loans are paid off?

Now that the backstory is out of the way, I have been tossing the idea around in my head for about two months now of whether or not I should use the money I've accumulated to rid myself of my student loan debt, OR, use this money as a down payment on my first investment property. 

Lastly, if you want to know how paying off certain debt (or doing other things) might affect your score, you can use a app/service like Capital One CreditWise (you don’t need to have a Capital One account).

You'll be expecting to put down 30% right now at about 3.5% interest on long term debt, or 8-9% interest on bridge/construction debt.

Under the bankruptcy trustee's oversight, the bankruptcy case can survive the debtor.

Is the seller financing the entire debt or is the seller financing a supplementary note?

50% is really high so the two main options are to pay down your debt or increase your income.  

The first step is to reach agreement with the investor as to whether the investment is to be debt or equity. 

Other ideas to get some creative financing:(1) HELOCs on US property which you can deploy as you wish(2) Margin loans against stocks/bonds(3) Junior Debt or Preferred Equity on a crowd sourcing website - if the numbers are that compelling
