Sounds like you have the motivation & ambitious but precise goals.

Once you're ready, create a goal (e.g., "I will buy at least one single-family home, duplex, triplex, or fourplex before the end of 2019") and then do it.

The multi family niche makes this goal possible.Keep pushing.

(Cash Flow is my goal) Pros/cons, other creative ideas?

I don't know the %, but I would still guess 90% washout or never hit their goals, but I do see some "graduate" and seem to do well long term. 

If multifamily properties in your area are priced well, it might be worth moving forward sooner rather than later.Risk Tolerance: Since you’re the sole provider, it’s crucial to ensure you have a solid emergency fund to cover unforeseen expenses, especially during vacancies or repairs.Long-Term Goals: Think about how this investment fits into your long-term financial goals.

If you ever want to connect and go over your goals, I'd love to do so! 

My main goal is it be able to retire at age 40 from my main job and work entirely on my real estate portfolio.

I have been to RE meetups in the past with like-minded everyday investors pursuing similar goals, sharing stories and learning from each other, running through numbers, sharing network contacts, and even doing deals together.

Hello everyone my name is Omar I’m 24 ,just recently came across wholesaling  and I started doing some research on it and it seem like it’s the best option for me now to get my foot on the door and eventually start doing flips down the road. since I’m new to wholesaling and barely know anything about it what books, YouTube chancel, podcasts, even a course that might help me get on track and learn the fundamental of wholesaling.I always come across some type of strategy of real estate that I might consider to pursue but I never end up staying consistent and taking action but my goal is just to learn about wholesaling and find a way to take action now.
