You likely need a much larger volume in lower cost areas to make the same money.  

I'm really interested in foreclosure/ pre-foreclosure purchases and have been studying on how to read court documents, title searches, and I have been watching the auctions daily.

It will all depend on volume. 

Anything that is almost guaranteed to be used daily in your rentals (i.e. couches, bed, chairs), I'd try to invest in as much quality as you can for those specific items.Some store sites will let you filter for "contract grade" or "commercial grade" items - these are the sorts of furnishing that get put into higher-use commercial applications such as hotel lobbies, apartment building amenity spaces, etc. 

Additionally, the multifamily millionairre volume 2 by Brian Burke gives you good insight into the large multifamily purchasing process, the associated due diligence and underwriting. 

Typically, management groups of this scale are VERY efficient and are maximizing revenue and NOI on a daily basis.  

We receive over a dozen calls daily from tenants desperate to move into anyone of our great rental properties.

I'd like to test out offering spots on the property to rent out on a daily basis that are entirely or close to off-grid or primitive.

The daily calls is a Facebk live stream where you can ONLY ask ?

They think it's unfair because they only shower once a week but can hear the upstairs neighbor showering twice daily.
