Maybe next the brokers will stop asking almost 6% above Libor for a loan that’s better secured than most mortgages. I get offers in the mail for unsecured personal loans that are better rates than margin from any broker besides Interactive Brokers. Warning about them though: I hear they are extremely aggressive on margin calls and skip right to liquidation so be smart.
That's only for the "smucks", though. If you have a proper banking relationship, you'll get great rates.
I learned this lesson recently. I had to go into a bank to get a prime + 0.5 line of credit secured against my home's equity. Nowhere on the internet would an online formula give me anything close.
