The goal is to achieve and maintain financial freedom.

People rarely achieve wealth quickly.

(These averages represent state-level data, and individual cities may levy additional taxes.)To achieve the same level of cash flow as a property in Nevada, you would need to generate a higher cash flow in Texas to offset the higher operating costs.

Hey Mitchell,Since your goal is to leave your 9-5 (achieving a certain amount of cash flow) then to reach that goal you can either have ~5 paid off rentals or ~20 leveraged rentals. 

I’m very bullish on Passive Investing and creating multiple streams of income (mailbox money as some would say) and see this route as an effective way to achieve that. 

If I HAD to pick one of your 3 options, I'd probably go with option 3 because it's likely the one that you can achieve the quickest... especially if you aren't concerned with cash flow. 

If a bedroom has two (or more) separate windows; one functions as intended but the other does not... the functionality/egress requirement is achieved via the functioning window, correct?

However, it does require solid expertise in digital marketing to achieve positive results.As for list pulling: you've got solid services like PropStream and Listsource to name a few

Of course, this is just my opinion but I bet I'm not alone..If I'm an investor, I think the returns you're able to achieve in Costa Rica are higher than normal because you focus on these large properties and, as @Martin D. mentioned, prices in that country are too high and returns too low.

You have to determine what your goals are and then attempt to achieve them.
