While I realize I'm tiptoeing on the precipice of paralysis by analysis (I once spent a month researching my coffeemaker), it seems like a pertinent discussion to have before I finalize my decision on which niche and strategy I'm going to pursue first.  

Welcome @Freddy Salazar, as your first purchase you might want to look at House Hacking. https://www.biggerpockets.com/renewsblog/2013/11/0...It has somewhat become my niche to help BP members go through this process.

I could have done it myself, but I wanted personal advice tailored to my unique situation and business strategies.

Sort out your colleagues, to easily find the people in your local meetup, other investors in your area, or go deep and sort them by niche to quickly find the agents or fellow landlords in your circle.

This is because (1) much of it is owner user, (2) much of it is unique and hence lack true comps (3) stays vacant longer as tenants are fewer and (4) needs are more specialized.Further, many industrial properties are extremely hard to lease if the current tenant leaves.  

How do you go about defining a criteria and focusing on a niche?

So after graduating 3 months ago, the army put me on "casual status", a sort of limbo that is very unique and basically only happens in this specific location.

What a unique job, James!

But then you limit the rental/buyer pool to that narrow niche.

Have others run into such difficulties with unique properties?
