I work as a commercial lender and my niche is typically loans over 5 million.  

  $300K in gross rents per month (I think that's what you mean) probably translates into a $30 million (+/-) deal. 

Or possibly a lot higher -- honestly, I am shocked everyday by what houses can fetch around here!

A primary market has 5 million or more people.

Everyone has a system to make you millions. 

I don't think the property amount/ loan amount qualifies for a non recourse loan, typically they are for 1.5 million and above.

I recently purchased a property at a Trustee's sale on a first deed of trust with an original amount in the $600K range, but the total unpaid balance had grown to well over $1 million!
