I had a difficult time narrowing it down to 3 biggest struggles.I agree with @Michael Smythe on #2.

I want to narrow down in B - C neighborhoods.Thanks in advance. - Q

Seems like a great way to narrow down the list then, the best GPs, managers, CEOs, will openly discuss their losses and mistakes and what went wrong and what they learned from it so less likely to happen again.

The sheer amount of topics and knowledge can be overwhelming so If anyone can narrow my search I would be extremely grateful.Some topics I know I need more info are:- VA Loan approval process- Living in Quad plex for 1 year then buying another investment property to move into.

Have to narrow it down a bit.

If you are going to invest remotely, I suggest narrowing down the regions/markets you are would like to invest in, then take each step of due diligence to figure out what that market offers, any downsides to not being local, etc. 

The easiest way to narrow down the best path for you is to decide how passive vs active you want to be. 

I've narrowed in on some areas I personally enjoy and at first glance seem like they would be good STR markets in the PNW where I live.
