Generally commercial loans are minimum of 30%, but you might be able to get a slightly lower down. They are almost always a variable rate based on something like LIBOR + some risk factor. Great credit and big down maybe 5% right now with a possible option to lock the first 3-10 years.
A lot of commercial loans will be based on a 30 year payment but a balloon payment at a 10 year term. They end up getting rolled a lot. So you pay a 30 year payment for 10 years and then have huge balloon 80-90% of the loan balance that you refinance. The pitfall is you still need a 30% LTV when you refinance so if the property goes down in value you might have to bring money to the table or let it go when the balloon comes due.
