Hi @Nikki9
There's no way to have a second administrator on the same account...
Yes, you can add his bank account on your payout method, wait for a couple days and on the payout rules you can setup the %% so the money goes automatically to his account...
You may wish to provide on the same page his ITIN/SSN so he will be responsible for his own income tax...
The only way he can access your account is by providing him your account credentials (email and password)... I would not recommend this...
You can provide him the iCal of your listing so he can sync with personal calendar and get all the information but he would not have control over your listing...
By a similar way I do this with my partners... I send them an email with all the details for each reservation I take.... But I would never provide my credentials, and I have already denied it a couple times...
