I have 8+ units that I would like to install plank flooring/vinyl of some sort when the units turn over tenants.

In other words, that percentage will only rise (unless prices begin plunging).Existing home sales rebound, sort of.

I recently joined pro and I found out that there is no filter to sort out multi-family in "find deals"...

There are very few banks out there that will allow a seller held second without you coming out of pocket or using some sort of collateral.  

I am also finding that there are all sorts of trash in the gutter in the street in front of the property.

Actually sounds kinda like some sort of fair housing violation 😬

I recently made a post about my favorite house hacking strategy which is to find a house that has a basement entrance or one that has some sort of side or garage entrance that opens up to the basement stairs and turn that into a basement entrance.

Some sort of management courses would also be useful RE is not only managing a physical property but tenants, handymen, skilled tradesmen, etc.

That's gotta be some sort of protection.
