You sound like a very motivated entrepreneur and we have to really discipline our drive to get on.

Each property has its own doc to help containing pictures, instructions, locations of all devices to refer to when guests have questions attention.

That means you have to make promises of instructions - and keep them.

Include safety rules, depth markers, CPR instructions, and emergency contact information.

But before I used then I would just sent guest message via airbnb and ask for their email so I could sent them directions and check in instructions.   

Millionaire real estate investor by Gary Keller and Confessions of a real estate entrepreneur are my two favorite!

Local embassies and chambers of commerce can also provide information about local investors, entrepreneurs, etc...

Prior to covid, County Office of Housing instructed landlords using the Voucher letter to screen tenants, because no two vouchers are the same.

You then register that LLC as a foreign entity with your state.Contact your Secretary of State office or review their website for instructions.

I would make it as easy on the tenants as possible Tell them to run it in the bedroom when they leave the house When they go back open the windows to air it out for 15 mins before going back in Best would be 2 + hours but even 30 mins is good I would ask them to also read the instructions  Best they could do it 5 times, 2 Hours  over the course of a week that would be great it leaves a really clean smell.
