Help! Trying to acquire a loan for a home with equity but -

[Anthum Deal]

I have a rental property with a $14,000 balloon payment due next month. It is worth around $70,000, plus has a good tenant paying $620/m.  I have applied for and been turned down for a secondary market loan from a broker and a bank loan from a local bank because I only have rental income and contract (gig) income. I also have 2 other properties to use as collateral.  I'm looking for advise on how to get a loan for this property when my debt-to-income is not what banks are willing to work with?
