Debt to income issue

[Richard A.]

I am looking to get a rental unit. I have a home with 50% equity. 600k. Owe 288k. My income is 90k that I can prove from my full time job. I have a side business that is profitable at estimated 50k for the year. Banks are not counting this income yet.  

I have zero debt outside the house.  With my property tax and mortgage I get denied for mortgages for the second property.
