I see a lot of options floating around.

First let's address a pro tip; the one that said glue down a FLOATING FLOOR which is all Click Lock.

Lets define A, B, and CThere are many definitions floating around attempting to define investment properties.I like to start with the community in which the properties is located.A neighborhood = 95% homeowner or betterB neighborhood = 65% homeowner or betterC neighborhood = All rentersThese neighborhoods could also be defined by the land value, on which the subject property is located.

This area never truly took a hit, but with the soon to be overpricing/overcrowdedness of Atlanta lots, I expect developers to heavily target this area (along with East Point) for luxury condos catered to millenials, actors/actresses, and movie directors, and those more affluent looking to be out of the way, but still in the mix if you catch my drift, and then some regular residential lofts catered to those who work at the airport, in the City, or those who pop in and out of the city at will.Your views on Cascade Ave are interesting though.

  * Returns were about 100% in the past ($200K total returned for $100K invested), but have drifted down to an expectation of 70% to 80%. 

- I've been quoted at 5.25% rate on the mortgage, but also given an option to float it until close in the hopes that it drops after the rush to refinance gets completed and maybe the coronavirus situation stabilizes (big if).

Not to mention they have some nice looking linoleum nowadays or even the life-proof floating floor.

It's an odorless fog that will not drift into adjacent apartments because vapor doesn't "drift," it dissipates so it can't leave any residue on walls or in carpets, etc., and you may even be helping some people to quit smoking cigarettes by switching to PVs.As for public/government housing authorities, the key word here is "government," which translates into "control."  

Summary is good tho but that article has floated around the web for years and has flaws.
