Another option is if you're already doing other flips or are definitely planning on doing more, you could take some time and shop for some deals on buying your own furniture and accessories (remember, great staging is much more than just plopping a rug and a couple couches in the living room-its really setting a mood with little knick knacks, accessories, art, etc) but often on craigslist you can find barely used decent furniture for some good or even great deals.

An ADU is an "accessory dwelling unit" - usually a garage or basement that has been turned into an apartment.  

Ryobi sells the little kits of like 100 bits that are a great accessory as well.

Basically, everything is done except for refinishing the hardwood floors, installing light fixtures, bathroom accessories (mirrors, towel bars, etc) and we are still waiting on the quartz counter tops for the kitchens and bathrooms to be delivered.  

I rent a licensed accessory apartment in my basement.

The garage looks to have a footprint near the size of the house... perhaps you could call it "Mancave with Accessory House"?

Signs shall not be placed on the wall of a residential building or an accessory structure.

The neighboring buildings house a sheet metal fabrication shop and a truck accessory business.Given the factory/manufacturing character of the neighborhood, the opportunity for a normal tenant seems nil.

Try to find couches, chairs, barstools, rugs, towels, accessories that will fit most styles of homes (whites, beiges, etc).

The technical term for that is called an Accessory Dwelling Unit.
