Where do I begin when creating my systems?

[David Reeves]

I have just under a year left until I get out of the military. The time is flying by and before I know it I will be doing my first house hack/BRRRR on my very first property. One of my primary goals for real estate investing is to make it as passive as possible for me. I do not want to miss my two girls growing up anymore than I already have. Where do I begin when it comes to creating a system? Whether I am creating a system for what will happen when I have a tenant leave and begin looking for a new one. Whether it be a system that is in place to find the best contractor's for the job. Where do I begin when trying to create systems that will be in place so that once I start my real estate investing journey I can feel confident that I have the proper systems in place to take care of certain things? Thank you in advance for any and all of your help.
