As Brandon Turner, one of the BP OG's advises, evaluate at least 10 properties per week to see if they are worth investing in/flipping/whatever your focus is because this builds your "investor muscles" so you will know a good deal when it comes up.

I would be the muscle and they are the $.  

You will be taking on more liability, and if you go bigger than 4 units you won't have the owner occupier financing available.Exercise your analyzing muscles by vetting some possible deals in different price points so you can see the difference in finances.

Saying no is like developing a muscle, the more you say it, the easier it gets.

Not purely as an investment but also an exercise for my design and construction muscles.

Once you are in more it is like a muscle the more you strengthen it the stronger it gets.  

Like working out at a Gym to build muscle you must leave one comfort zone for heavier weights, e.g. put down the 20# dumbbells and pick up the 25# dumbbells and then the 30# dumbbells.1031 Exchanging is no different.

I need to flex my capitalism muscles and get stronger.

Put muscle to it.  

So for me in majority part I am just scratching an itch, and I am exercising a muscle.
