Do u intend to use it esp during the peak times?

I think the best thing you can do is help them understand the 'why' behind using this method.As I'm sure you know the BRRRR method is very popular because it helps increase the speed at which you can build your investment portfolio and investment income.If I were explaining this to a family member I would compare the traditional way to invest in real estate vs. the BRRRR method.Traditional- Buy an investment property, let the tenant pay the house principal down.
