Expenses unique to short term rental:- Utilities (trash, water, sewer, gas, internet, tv)- Cleaning and prep- Consummables (soaps, towels, linens)- Hotel taxes (this depends on your locality)Also, to Rob's point, it is more management intensive than long term rental. 

The poor fellow can't have his bar of soap until he pays $1.60!...

I will put up a shower curtain and rod, bath towels, soaps, and make sure there are either blinds or curtains on the windows. 

I also start them out with the basics in the house such as a roll of toilet paper, paper towel, shampoo, conditioner, and soap.  

The big issue I found when researching it is that you need to buy soaps and plant plants that are compatible with one another - this would be very difficult to enforce with tenants.

I have always used hot water and Dawn dish soap.

Multiple units or properties elsewhere (or even in CA still). 

Vacancy - Rent rate and occupancy rate go hand-in-hand - monitor REVPAR per weekday/weekend/month to really know how you're doingutilities including wifi and surveillance - ideally with remote monitoring and locked in at reasonable temps, smoking/noise/party detectors perishable supplies (paper, coffee, soaps, etc.), linens (towels, sheets, comforters - they need to be thrown out every 3-12 months), Lawn care - not just mow and blow, but garden beds tooPest control - 80/qtr furniture - it doesn't last forever.Maintenance - normal + changing light bulbs, fixing furniture, loose doorknobs, etc.Administrative software - dynamic pricing engine, guest communication system Hosting fees - this is not a passive model.

The worst are the ones who insist it's going to hurt their pets.Call the landscape company up and ask if they'll run a 95% white vinegar and 5% dish soap solution mix through a separate 2-gallon sprayer if you buy it for them.
