One key ingredient that you may be missing is forced appreciation ... if you were able to pick up that 4-plex at $70k because it was run down and vacant, then spend $30k to fix it up, put tenants in there, and be all in for $100k, but the property at that point would be worth $140k because of improvements ... yes, this type of thing is a lot of work to find these types of deals and remodel them, but those are the kind of numbers that get you in the right direction, speed up your progress, and supercharge your profits.

I think the most simplest way I can put this is it was just blowing my mind that (in this example in a market like Boston) private lenders would be giving you 300+K in order to invest it?

simplest answer to your issue...You can know every statistic, fancy book terminology, whatever CORC, CCO, OKREL, f, etc, means, but...that isn't worth anything if you arn't cashing checks every month from it.

The simplest answer is to calculate what your additional interest expense will be due to the refinance (say an additional expense of $3,000 per year), and compare it to what your annual return will be from what you do with the money.

CoCR is the easiest, simplest, REI analysis there is.Cash, only cash, no cash substitutes, for the first year only.               

Preheat the oven and mix the ingredients.
