Commercial Loan on Real Estate?

I need a loan for a commercial property, valued at $5 million, but with specific concerns.. The property already has a 70% loan on it which does not allow junior liens. It is held in an LLC and generates plenty of cash flow to support another 10% debt. I would like to borrow money in the LLC. The loan can be secured by the LLC, but not an actual lien on the title of the property. I also do not want to personally gurantee the loan. Any thoughts about what I might be able to get?
