Best way to finance a larger 10+ multi family building??

[George P George III]

 I have been kicking the idea around in my head on buying a larger 10+ unit building and most of the banks have either said they don't finance on larger than 4 family or it would be a 5 to 7-year balloon note that is then amortized over 20 years for payment and than renegotiated after the term. I just would like some insight on what you all have done that works and what options are out there. 

Thank you.
