There are old style martial arts that are outdated for todays times and then there are progressive martial arts that use techniques for real world self defense.No legal advice given.         

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

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.

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...

I would also prepare to sell it on the used marketplace but if you absolutely don’t want to go that route then I would recommend getting it included in the purchase upfront (but still use it as a bargaining chip first).3) marketing: the best target audience is going to be a savvy house-hacker for a property this style.  

I respect buffets prudent style and extensive due diligence.

Also, there are more things to consider than max ROI.Most people start by picking a particular type/style of property that they like for some reason (usually a gut decision).
