I have an equity partner that brought all of down payment to the table and the debt is funded by the previous owner of the property.

That's why  commercial property is priced on a cap rate, assuming it has no debt.   

But, it is coming up as debt for me...

My husband and I own our businesses and are concerned about the debt load. 

Might take one some credit card debt and risk having less than amazing people living next door but at least can rent for around $1300-1600.

Below are some additional ideas I have to come up with my 20%:Interest only debt partner with a healthy interest rate (roughly 10%) for 3 years.Using another property I have (7 Unit) as collateral.

So not adding to our debt, but pocketing cash and paying off debt that way.What would you do and why?

Your credit score will help - Lenders don't want to lend to owners with history of bad debt, etc.  

Additionally, my credit history is fairly young (although good, between 720 -770 depending on where I look) since I only moved to the US three years ago, I have no consumer-, student-, or car-debt, 100% payment history and no derogatory marks, but the Banks I inquired at either don't have LOC for investment properties at all, or my income is considered to low on paper, and I am trying to access some of the equity sittingThanks in advance for taking the time to answer if you can help!

Unless your credit is not great, or your debt to income ratio is throwing you off.
