In addition to doing the math to figure how much you'd profit, you need to do the math to figure where the break even is. And, here is the important part; know at the very beginning you might need to bail out if it gets to the break even level-- and accept all the consequences.
I am very bullish on ORC. I am a believer. Even still, I would divide up that 100K amongst several dividend payers; ORC just being an outlier that pays the most.
NEVER EVER EVER Take a RISK (Even if close to Zero) with the EQUITY of your home in Any investment. Use any other money but Never take a risk with your equity. That is your home.
My 2 cents if you care to.hear it.
Good luck
I am strong believer in ORC but would never do that or any other stock.
