Neither includes "virtual" return terms and rationalizations (appreciation, tax savings, etc...), but CoCR is just cash.  

And do read 4 Hour Work Week by Tim Ferris, because virtual assistants can do this for you.

-Get a non-FHA mortgage, pay the recurring PMI at first- knowing it will (hopefully) go away after I've built up 20-22%+ equity in the property.Assuming consistent PMI costs and interest rates between options (before &/ after refi), the only scenario in which I can see the second option being more beneficial is if I had put enough money down to hit that 20-22% equity level within the first 12 months.This seems implausible due to mortgage payments barely paying off any principle in the first year, not to mention I'd think the only way I could attain that level of equity so quickly is if I had put down 15%-18% initially, which virtually eliminates the benefits of a "low" down payment.I don't have any specific properties, institutions, or rates in mind, and while I'm sure these questions would be more easily answered on a case-by-case basis, what are some considerations I may be overlooking?

However, if you already have a balance in Roth IRA by converting that into self-directed as Brian mentioned you can have better control over those funds and virtually limitless investments choices. 

Virtually everywhere is at market peak right now, there's a good chance it doesn't make sense, deal wise. 

I would rank taking a cash advance to play basic strategy Blackjack as a better decision.

(300,000 * .07 = 21,000 – 3,000) The 30,00 being the simple interest we are supposed to pay.It’s not a ton of money I know but it’s enough for me to want to pose this question.Now totally I get it, the stock market can crash 10-30 percent in any given year like in 2008, 2001 etc… But even if it did, it has always recovered within a couple years and the chances that there would be some mass exodus from your 200 apartments with everyone demanding their deposits back at the same time and you not being able to refill all the openings is virtually nil.  

I had to make quite a few calls when I first looked but I found a lender that would go down to virtually nothing, I think it was 15K.

I couldn't help but notice the virtual knockoff of my prior townhouse project interior design.

As the subject suggests, I have virtually no real estate experience.
