Hi Melissa,
Every host has a different location, size of property rent out either shared rooms or full homes/units, nightly rate varies by area and demand, and amenities in the area and with the home. My thoughts on this, is going to depend on the monthly rate you charge your guest, and what's Included in that rate.
I have had over 500 stay in the past 6 years between a couple platforms guest can book through. Let me tell you, I lived and learned the demographic of that travels to my area, whats bringing them to my area and figured out when peak and slow season was based on my bookings . I have had to adjust my rates and what I include in that rate that I provide to guests.
It's also important to provide clear expectations for short term and longer term renters in your listing and in your home, on house rules, things to do in the area, and what you will include with the rate.
This will determine if it makes financial sense to include toilet paper, laundry detergent, shampoo etc. Trash bags are inexpensive and I feel it's a must for anywhere you have a trash can inside the home as it keeps it more sanitary. I would definitely keep a box or roll of trash bags under the sink in that bathroom. In common areas of a shared home, it makes sense to keep the kitchen stocked with paper towels, dish soap, and trash bags.
Something to consider that has helped me a ton. Is creating a cute way for guests to visibly see house rules, any type of instructions you feel is important for them to know around the home (you can laminate or put printed instructions inside different side picture frames, that can be hung on a wall or placed on a counters or table around the home. What worked for me was printing instructions for what I provide in the kitchen, such as coffee, and creamer (if you off that), disclose kitchen rules, such as what you expect your guest to do with the pots, pans, plates, items after they cook. Do you want them to Wash certain items by hand or can they just put straight in the dishwasher and do you expect them to put their dishes away once they are clean or will you do that part ? Having a shared home where you rent a room and share common areas. Think about what you would expect out of a roommate, and your rules/expectations will starting coming to mind.
Also important to consider having in your listing as well somewhere in your home, in the are answers to the below questions..
Can your guest bring other guests? . If so, how many guests can come visit your guest for the day?
Do you allow guests not on the reservation to stay overnight ?
Do you allow smokers? if Yes, but only outside- then where can they go- the front or the backyard?
Make sure to have clear rules on pets, if you allow or don't allow and what you expect.
Do you allow your guests to use the common area such as the livingroom anytime of the day/night they choose, can they have other over to hang out in the common space ? If so, do you have quiet hours ?
where do you allow your guests to park? Garage, driveway and/or steeet?
It's all about clear communication and written instructions printed out (I laminated all mine) and used double sided Velcro traps to take signs by my coffee maker, one with wifi code, trash days, and check out instructions located on the back of the front door. Office Depot)
