Quickest way to netting 10k per month??

[Ryan Good]

Hey BP!! I'm new to this world and I'm excited to get started. My goal is to replace my current income of 10k per month, now I realize there is going to be many ways to get there however I wanted to get some feedback from you guys and gals. What is the quickest/best way to get to my goal of 10k net per month? I have 40k to start with. I'm attracted to multifamily deals as of now but want to remain open. I would like to have them with a property manger if possible because I'm also running a trucking company.  Feel free to ask questions on my scenario.. Thanks in advance !!
