What is the most outrageous interest rate you've ever heard of for a business mortgage loan?

Answer 1

35% in the old days they used to call these people loan sharks.. now they are called 'lenders'

Answer 2

I believe in Canada anything over 60% is considered illegal. So what pay day loan companies or loan sharks will do is quote a smaller interest but add on an admin fee which ineffect raises the rates back up again. It's all smoke and mirros to basically stiff you with huge interest payments
