Each entity has different "policy years" (which do not align with calendar years).

I use Homeaway.com to advertise, take payments, manage my calendar ect.I also have an AirBNB account but it doesn't produce many vacation rentals.I have a great housekeeper that I text to schedule my cleaning.I use a Lockbox for keys.I have 2 Honeywell 9000 series thermostats to adjust temp when no one is there.I also just recently installed a camera system so I can see who arrives and make sure no one is breaking in when vacant.Very easy to manage remotely once everything is going.

I will check my calendar for availability. 

I am fine to continue updating the calendar and replying to guests.

I will check it out and put it on my calendar!!

You can assign multiple Labels to an email/calendar/etc.
