from banks right?  banks are lending $100 for every $10 of book assets, so they can offer a lower than market rate.  

No one that actually had to earn the money would risk it for 5%

True market interest rates are probably 10-13%, if currency is inflating at 8%, the risk premium is 2-5% which seems about right for a low risk loan.

Sorry I am thinking of rates here in Canada. You can borrow secured around 5% and  unsecured around 7.5%.
