mortgage broker a good choice- he will have many choices for you, from savings banks to insurance company loan programs.

you will likely only get 70-75% LTV, so will need equity for the balance. most commercial loans will balloon in 10 years.

the terms will also depend on your ability to personally guarantee the loan, other assets which could back it up, other income as collateral.
the real property will need to appraise at nearly full value, as well.

good luck
