I've been reading lots of articles and books about multifamily investing and it seems like these will be a great supplement to what I've read. 

Instead, use it to supplement your other marketing efforts... in other words, use zillow as a way to reach sellers, but also scrap craigslist for sellers, send direct mail to absentee/high-equity owners, etc.    

I will do some of that but after listening to some BP podcasts and doing some general Googling I feel that I can supplement my income nicely in the flip or rental game.

The mortgage payment, taxes, insurance, etc. would probably run me about $1,100-$1,250.Given my personal budget allows for $1,500/month in savings, anyway (plus a discretionary allowance I could tap into if needed), I feel like I could handle vacant months without feeling the squeeze.I would definitely use a property management service — the combination of my inexperience and my long work hours (often 70-90/week) means I am simply not the best candidate to manage property on a daily basis.I'm not looking for supplemental income out of this.

Whereas PITI would be $3800 and I would be able to use the tax advantage of ~1000/month to help supplement that.

I know this is a very broad description but I wanted to make this initial post to get a reality check, encouragement, hear from others who have done the same and been able to supplement their long term financial health and freedom etc. 

In order to supplement my education, I started watching Youtube Videos on Investing topics such as: finances, stocks, precious metals, commodities, Rich Dad Poor Dad, building wealth.

You will need to be able to afford to supplement your tenants rent long term.

I would like this investment to supplement my current income, and over 10 years build a sizable real estate portfolio that will allow me to leave corporate America and spend 100% of my time focusing on growing my units.

And if you are trying to supplement your income with rental property, its gonna take a few units to make much difference.
