@John Cohen is a pro when it comes to large and mid-size multifamily properties.  

You won't have a chance at this, just unrealistic....no money, no credit, no experience with this size properties.  

Hey BP community, My name is Rhea and I'm looking for a mentor, someone to invest a significant portion of their time and energy to teach me all you know.

I'm not sure what the regulations are for how many mobile homes I can put on that property for the size and traditional websites have no data for the rental market in that area for me to gauge the market for myself.  

Those added to the loan basis are ANY cost associated with obtaining financing including lender's appraisal, credit checks, origination fees, lender's portion of insurance, etc.

Like @Steve Babiak mentioned, call around to small-mid size community banks and see if they will entertain 20% down.  

Depending on the size of your units, have you looked into ductless air conditioning?

It seems as a safe and good plan in long term... but what would happen if the economy cracks again (I dont see the economy such an stable thing nowadays) a % of people loses their jobs, the vacancy rate rises, and the values of the property goes down and you still have a big portion of your mortgage to pay?

This is what will be taxed by federal, state, county (at least here), and the self employment portion.

$1,000,000 would be the loan size to generally be considered for non-recourse.
