This is probably the most you can do for him without getting involved in this soap opera.

I'm looking at buying a 4-plex in Grant County out near Ephrata in a place called Soap Lake.

If you don't disclose...don't drop the soap.

I'll hop off my soap box now :)

Soda Machines, Laundry Soap Dispenser, Arcade Machine, Candy Machine!  

Since it came from more than one person, I wanted to address it and spent 2 weeks cleaning it - disassembling the front door of the oven, cleaning the glass surface and putting it back, cleaning the oven rack, cleaning the stovetop with bleaching powder, soap, blade. 

(OK, getting off soap box now.)

We use the app called breezeway for these lists and these lists include things like, are there ample towels, dish soap, laundry detergent, etc.

But I don't know how much insurance, airbnb commission, consumables (soaps, paper towels, etc.) will cost. 

Clean hand railings, clean HVAC vents, use wood soap on the kitchen cabinets, etc.
