1. Yes, you need to find out if renting your home on a short term basis requires a permit or license from your municipality.
2. Yes, you will receive a 1099 from AirBnB (unless they get another pass from the government as they did in 2022 -- so keep your own records!)
3. Your personal possessions and items that you do not wish to share with guests should be packed or put away in a safe location - a locked garage, a storage unit, a room in your house (deadbolt!!!). You are renting the whole house, not just a shared room with you hanging out too, so your presence through belongings should be minimized.
4. Talk to your insurance agent. Your homeowner's policy will probably NOT cover you for damages when a renter is in situ. In fact, renting through AirBnB may cause your policy to be null and void, even if the damage were to occur when no guest was present -- i.e., just listing your property on AirBnB may void the insurance contract. (And AirCover is NOT replacement insurance for your own policy.)
