I will have furniture as soon as my interior designer (wife) gets here with the furniture.

(For that matter, DWV plumbing is much more complex than electricity or water supply, but I digress.) 

The small up front cost for the machine ($300-$1200) and the whole sale purchases of supplies (alibaba or other dropshippers) is peanuts compared to how much you can make from this thing long term.

Outside items (like furniture) are subject to expanding and contracting as well as anything subject to moisture or mildew/mold. 

The tenants supply their own appliances, take care of the grass/snow, pay their own gas, electric, water, sewer, and trash.

At some point, probably when the building was turned from a single-family to a multi-family and the utilities were separated, new supply and return lines were run from the boilers in the basement to baseboard heaters in the apartments.

So, supply and price are starting to move.

The investor has to buy the supplies to rehab the house and is either spending his time fixing up the property or hiring someone to fix up the property 5.
