Typical commercial loan for 8+ Unit Apartment in Los Angeles

[Joe Yeh]

Curious as to what a reasonable percentage down would I need? 

I don't have steady income so I can't rely on my work to get the rest of the loan. As in, I'll need a commercial loan, based on the current rent of the property.

For example, for a 3 million dollar 8 unit apartment complex, am I looking at 20% or 40-50% with current interest rate levels?
