Need to remodel 4 bathrooms, 4 kitchens, and paint all the walls and do the floors.

Still updating a few things like kitchen, floors, bathrooms, curb appeal.

Growing up poor in a house with no windows and dirt floors, I know how blessed and fortunate I am to have the opportunity to chase my dreams in this great country!

According to the seller they can be either, due to there being a firewall from floor to ceiling, but also one roof and 1 foundation. 

Floors: Sweep, mop, and wipe down all floor surfaces, including underneath appliances.

In my area in NJ a single family house rented to one family usually does not cash flow.I am thinking about buying a house from 2 retired brothers who live in single family house: one brother lives on the top floor and has his kitchen, bathroom, 3 bedrooms, etc. and the second has similar setup on the bottom floor.

Your money is still in the property, and takes the form of bricks, siding, floors, etc... 

@Zoran Domazet & @Will Barnard - not an expert, but being in Florida (where sink holes are frequent) and seeing "polyurethane to fill a void" (polyurethane being an expanding foam with little load bearing capability) makes me thing that we are not taking about a small crack in the floors/walls due to foundation settling, but something more vicious.
