Not sure I can add much to what’s already been said but… Definitely check the insurance situation where you live. Where I am, car insurance is done through the government and if someone drives your car more than 12 days in one year, they have to be listed on the policy. It’s a bit of a pain because you have to pay for them to be added for the rest of your policy and then as soon as you are able, you take them back off and get a refund. Would get exceedingly expensive if someone did not have a clean driving record. I have a couple of times had the sitter use my car, once for more than the 12 days so I did pay for their insurance on my car and the other was less than 12 days so I didn’t have to. I also make sure that they have a good dog cover for the backseat of their car, a couple of old towels, and I give them money for gas for taking my dog to a dog park if they’re using their own vehicle.
I say that they are free to use any of the staples in the house, and even things like coffee, tea, eggs, any fruit or vegetables that I have left And that they do not need to replace these. I do make sure there is space in the fridge, the freezer, and a cupboard, for them to put their own belongings.
I also make sure that they have closet space, including a folding dirty clothes hamper, two or three empty drawers in the spare room where they sleep.
I always recommend being very upfront about expectations should something happen to a pet as to whether they should euthanize or pay that bills which of course I would pay back, if they couldn’t reach me right away.
Also being upfront about how long your pet can be left alone, one thing I do is ask a neighbour if they are able to come over maybe once or twice depending on the length of the time so that the sitter can go away for a longer period of time.
I always point out which neighbours they can go to if they have an issue in the house and can’t reach me right away. That’s also a very nonchalant way of letting them know I live in a neighbourhood where people keep an eye on what’s happening at each other’s houses! And of course I’ve already given them the information about things like the water shut off valves.
I cringe when I read sitters, make comments about how they take pictures of all of the cupboards to make sure they put everything back in the same place! I assure sitters that I am not going to have a fit if they find a better place to put something in my cupboards than what I do.
I aim for good communication, and that includes when I’m sitting at the ferry terminal, and I realized that I haven’t emptied the dishwasher… And I’m texting the sitter to apologize.
