BRRRR strategy work indefinitely?

[Michael McManus]

As a newbie here, I'm trying to understand the BRRRR strategy more. If I buy a property using this strategy and it works out that I can get my investment back to repeat, I should be able to just keep going, right? I feel that at least for the time being this is the best approach. My wife is very hesitant to use our money and if I could get back the initial investment after a refi it'll probably get her on board pretty quickly.

Just kind of thinking out loud here.  I'd love to hear your thoughts/experiences.
