Best type of loan for 600k mixed use multi

Hi,

I'm trying to close on a property that's around 600k. It will be a mixed use multi, 6 residential, 3 commercial units. 

I have only done SFR before and not sure what type of loan works best for this. It looks like commercial loans are for loans of at least 500k? We can do 25%, so we would need a loan for 450. Any advice here would be great!

Thanks,

Tony
