After you are conditioned to it a little bit, you get used to it and it becomes acceptable because it is the trade off to be in a place where you can do what you want, within reason. 

In my area if you advertise a trade your not licensed to do you can get up to a $10,000 fine. 

You're CoCR is a great metric for one of those 4 methods, but it might be better to look at your entire ROI.For example, I have one property that I bought for $99,900 with 20% down plus closing costs, which came to $21,609. $1,245 (Rent) – $549 (PITI) – $124.50 (PM) – $124.50(CapEx + Maint.) – $43.92 (Vacancy budget) = $403.08 Monthly Cash FlowLooking at my CoCR, that comes to 22%.

A tenant that is Johnny-on-the-spot with keeping up my property, pays on-time every time all the time, and virtually never calls, is worth something to me, and I'm willing to trade some dollars for that tenant.

Also, is this essentially the BRRRR method?

These are traded in USD or, sometimes they sold by the developers in pesos (MXN) when they're primarily marketed at Mexicans.

I'm a rookie investor who has come across a deal that seems to work well, but I could use some assurance or advice.  Here's the sitch...I come upon a property in Alabama from a wholesaler for 37k.  Rehab estimate is 2...

It sounds really good and it excites the mind because you're going to get a business that's going to borrow the money but in practicality I just don't see it in the market like what they say it's going to do for you.A lot of times what you get with these gurus and these educational programs that you spend thousands of dollars for or that local ria rep who's going to tell you that he's the king or the or she's the queen of something all of these methods that they're using you got to remember they're on the circuit to make money and they're not making it because they're executing on their strategy they're making their money because they're selling you on the strategy.

Like with any choice, there are trade offs. 

IMO the best options are the trades (carpenter, plumber, electrician, HVAC--and those skills pay dividends if you go into BRRRR or flipping later), or, an IT path where you can start out at a decent beginner wage in a help desk or call center, use some of that income to invest in certifications, and then use the certifications to get the next higher paying IT job.
