I'm a recent college grad looking to build a steady stream of passive income outside of my current job.  

"Good Debt" works when tenants pay the rent, but good debt becomes bad debt when that rental income stream dries up for any reason.Some people thrive on going through the rags-to-riches-to-rags-to-riches cycle multiple times ["nothing ventured, nothing gained"], but for me, I believe the slow-and-steady-wins-the-race approach of the tortoise over that of the hare.

Books and magazines I am at least going to open and look at every page to my right, Amazon Prime music streaming my favorite play list over my Echo, and cats more or less subdued... which is strange because their feeding time in only 30 minutes away...I am not proud to say this intimidates me.

The irony is 95% of investors are not full time....meaning they have W2 income to cover expenses...and living off cash flow from RE alone is very risky (you must have other revenue streams). 

Note that our clients buy long term, tax advantaged, inflation friendly income streams.

My day job is Marketing Director for an international tea company, but I'm looking to add an alternative revenue stream. 

While I am younger than Patrick I am on the same track as he is ( I am 45 and currently manage 15 properties while working full time)  And would like to most likely exit completely at age 60 and find something truly passive yet still give me as close to the yield I am generating now (between 14 and 22% annually) I don't expect to get the returns I am making now on my rentals while self managing but at age 60 I hope to scale down my cost of living as well and not require as much, plus I will have 401k as well as social security so my plan is to have multiple streams of income. 

Anybody have any thoughts on paying for cable vs. netflix (or other streaming service) in an Airbnb?

This is another income stream but it's useless if you have a small operation.

If the MLS shared their data stream, then Zillow would be properly updated.
