It is a good thought process to undergo early--about deciding on your key strategy (to buy hold versus flip)..... and the flip versus buy and hold does tend to entail different goals and philosophies and even skill sets. 

My philosophy is buy hold and turn into short term vacation rentals.

I attended the 3 day event, and while there was no way I was going to put 27K on a credit card for their mentorship, I was fascinated and hooked on the philosophy of cash flow.  

Physics, statistics, philosophy and evolutionary psychology are easier.

My philosophy when looking at investments in Houston suburbs is to assume no appreciation and no rent increases.

I disagree with the "invest in your own backyard only" philosophy.

I made my first investment with a Memphis based company because I saw great videos of the founder explaining his philosophy.

I also put in beautiful landscaping.My real estate philosophy has been to get it for the right price - sweat equity - so I can rewire, replumb, new roof, etc. depending on the age of the home and what has been done. 

They provide a new way of thinking about money, a philosophy if you will.

Pros and cons and both ends for sure, just depends on your philosophy and your goals.
