Their honesty, integrity, character, etc.    

But in Los Angeles theres strong competition and if Im going to do this I need to be perfect spot on.I have tons of "other" agents letters and post cards , so I know very well what my competition is doing,

If you study, connect with others and perfect your process, you can be better than everyone else.

I decided to order a second report camera test (a month later from the previous plumbing report) from a reputable plumbing company as to the integrity of the plumbing under the slab of my new rental.

Let's assume everything does always go perfect with a property (it never does) and you don't have unexpected expenses (which you will), that cash-flow is something you could be saving to put into another deal down the road.  

@Grant Anderson, You're looking for a portfolio product that is a perfect project for a local community bank or a local private commercial bank.  

Perfect location for a rental.

In addition, if the inspector finds something that looks less than perfect, see if you can negotiate the price of the deal down.

Great explanation and makes perfect sense. 

Resulting in analysis paralysis... where you spend more time trying to get everything perfect, but no action actually happens.
