Learn what each one of these are, and see which makes the most sense to apply to your specific financial plan. $150 cash flow on any rental especially a triplex is dangerzone imo. 1 month of vacancy of 1 unit could destroy a years worth of financial gains.  

It would help if you could be a little more specific about what you want to learn.1.

You might consider other strategies, like taking a home equity loan or refinancing to fund repairs, but consulting with a tax professional or CPA would be the best next step for your specific situation. 

If there's any specific concerns I could address I would be happy to. 

@Tanya Maslach "I came away with several neighborhoods in Ohio"Ohio is on my radar for MTR, specifically rural areas in Columbus/Akron/Cleveland. 

•Are there any specific neighborhoods or zip codes to target or avoid?

3) Any specific states you recommend to set up any of these (Not sure where I'll be purchasing property yet, maybe Detroit, maybe Cleavland, maybe Augusta, maybe Des Moines, maybe Saint Cloud, maybe Memphis...)4) I already have a LLC based in Hong Kong (We call them limited companies, but the principle is the same).

Feel free to call if you have a more specific question.

Scaling-  your question is both country and even town specific.  

Just because you want to hit a specific number doesn't mean the market will meet you there.Great example of how Class C properties may appear like great cash flowing investments on paper - meaning fully rented, paying on time and normal levels of maintenance.
