yes the annual compound interest is high, but it is a short term loan for just a few months. Imagin Neke and his "250k to a million" thread, what if he could get 600, or 900k more in leverage...your talking huge weekly gains/ losses, that'd more than cover the 5.25% fee. perhaps a 0% same as cash deal would be better, where you only pay interest on late payments.
CM69, You've always seemed like a decent guy. But I gotta tell you you sound like you're hoping someone will tell you that's it's OK to take the money because that's what you really wanted to hear all along. IOW you're not looking for objective opinion. That in itself is cause for concern when considering increased leverage.
