@Geddy3 @ @daniellealberta have got you started with some good advice. This is a business and you shouldn’t go into it without research. Many areas are being flooded with airbnb listings making competition difficult. Also, yes, the upgrades -they often are more than you would expect. Be sure to have plenty of sheets, blankets, towels, and pillows, so that if a guest ruins a bunch at once you won’t skip a beat.
Are you going to clean it yourself? Do you have a flexible schedule so you can handle emergencies, should they arise? If you do plan to clean it yourself, will you have a back-up plan in place so that if you are ill, or need to be out of town, you have someone to cover it for you?
What income tax will you be paying? What about sales & occupancy taxes? Does airbnb collect them in your area, or will you have to do so? What will your insurance rates be?
Do you have savings to cover the rent during the off season, or when you don’t get bookings? Do you have funds set aside so that, if they should trash your place, you can get it cleaned and ready or the next booking, replacing broken glasses, etc., so you can present a perfectly clean place to the next guest, as if nothing happened?
Do you know other hosts in your area? You can shop the listings. Do a search without dates, and see what places, that are similar to yours, are they booked, or not? What are they getting per night?
Read all the old posts on this forum; they will give you an idea of what to expect.
Good luck! I wish I had the nerve to invest in another property!
