If you end up starting your own business and getting out of your current job, you'll generally need to provide 2 years of self-employed tax returns to support your income.  

Are you cash flowing the property?

We're looking to get out as much cash as possible, is 80% possible?

Just a heads up.So you calculated out you need  $6 million worth of apartments to hit your goal.A commercial loan may require 20% to 30% down in cash, cash reserves, working capital, and closing costs.You will also need earnest money cash.The lender may also require certain repairs to be done Shortly after the loan is made.The lender may also require the Property to be stabilized as far as occupancy percentage is concerned, leaving little on the bone as far as sweat equity.Good Luck!

If you can get one which cash flows it would be worth it.

Even if there is a due diligence period, that is material information that should be provided up front. 

I'll provide some suggestions below.2.

An all-cash (or hard money plus cash) offer definitely helps as well.Good luck!
