You might need a crevice tool, and healthy back muscles too. 

I think so, I do think it can be developed, honed, and strengthened like any muscle.

Synthesis is the analyzer I am using and many fellow syndicators I know use.

They potentially are trying to hide something by muscling their way in.  

@Richard Nassour: There are many tools out there - Michael Blank, MFA, Next Level, Synthesis, etc..

Like anything, it's not about the game it's about the practice so you have muscle memory to make the right decision in the game without thinking.If you look at anyone at the top of their field they have some type of coach and/or mentor, no brainer in my opinion. 

And just like so many Bigger Pockets Podcasts and books, I will read and reread until it becomes muscle memory. 

And it's a new muscle for you to exercise, so expect it to be weak at start.

You'll learn more from doing one deal that is yours than you will reading about what others have done/might do.You'll build a whole new muscle group based on mistakes, missteps, failures and eventually, successes.
