However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

From using data to identify emerging markets to building tools that automate property analysis or management, your skills could really give you an edge.

I recommend a few things:  define what you want to achieve and why investing in the US is the vehicle to achieving that ROI. 

@Jeanette LandFrom my experience working with over 400 investors, growing your portfolio with limited capital is absolutely achievable with the right strategies.

With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.

I'm also working on a Google Data Analyst certification to bring in some extra income while I'm home with our 19-month-old daughter.I'm still pretty new to this, though, and I'm not sure where to start or if I'm on the right track.

Visible is part of Verizon and has unlimited data for $20/mo. 

do you need help obtaining the data you are talking about?  

That said, I'm grateful for the alternatives you present--you're keeping the bottom line in mind, so I appreciate your help in exploring options that achieve the bottom line for the investors. 

That's only achieved with QUALITY.
