In order to avoid wasting time on a bunch of individual showings with unqualified applicants, perhaps consider doing what I do and host “open house” style showing windows. 

Hey @Zack Rosenbaum,That's high but it also depends on what style of building it is, square footage, whether all units have two means of egress, etc.  

There are old style martial arts that are outdated for todays times and then there are progressive martial arts that use techniques for real world self defense.No legal advice given.         

Quote from @Jon Martin: Quote from @JD Martin:  I've got a long enough history with LTRs to know that generally you don't want tenants doing more or less anything because it's amazing how little common sense a lot of people have, and this translates into not asking guests to do chores because 1) they've paid a cleaning fee, 2) it's a vacation even if it's a home, and 3) guests that do chores might just put dirty towels back on shelves and dirty dishes back in cabinets. 

Should I notify the current tenants in advance of each showing, or would an open house-style showing be more appropriate?

There is no Mid-Term or a Rent by the Room style loan as of yet. 

I then spent a majority of my free time learning as much as I could on the different styles and strategies that have been utilized in the past, reading everything from Lynch’s One Up on Wall Street to Graham’s Security Analysis, to learning how to build out financial models in excel.

@Chris Pomerleau thanks buddy, if only I could get my fashion style as synced up as you I would be unstoppable!

look at other STR data in the area and do similar style to do your best to recreate similar results 

Tan/brown neutral , and yes a little darker to hide stains....and not a Berber loop style, those look nice but are prone to damage...
