I’m doing research into larger properties. I’m trying to find a good resource to see typical financing options for a larger complex ($1m or more) versus a single family or duplex ($300k in my area).

Are these typically a 20% down payment with payments on a 30 year schedule, or is it more common to find loan that is interest only for x years with a balloon payment at the end?

@Derek Meyer   A typical commercial loan could require 25% down.  There are 30 year fixed rates avaliable.

If you have loan amounts of 1 million or more, this plays right into Fannie Mae or Freddie Mac's wheelhouse. They own that market of 1 million or more on the loan amount for multi-family. They can go to 80% so 20% down at rates in the 4s on 30 year terms. You wont find any better financing than that for these types of properties. 

The property will need to be in good condition and fully stabilized, meaning 85-90% occupancy. If they need updating or rehab, you will need to take them down with a different lender to get all that done, before you refinance them into Fannie Freddie. The other lenders will want 25-30% down. 

I hope this helps?

For loan sizes under $1 million, you will most likley be using a local bank or credit union. The terms for these loans are usually; 5, 7 and 10 year terms. I have gotten longer but this is normal. There will then be a balloon payment at the end. Down payment is usually 25%.

For loans sizes $1 million+ on a stabilized property, you will most likley be using agency debt (Fannie/Freddie). Their terms are; 5, 7, 10, 12, 15 and 30 years. Down payments are usually 20%-35%. Interest only is available from 1-5 years.
