Airbnb and LLC - setting up business bank account

Hello!

I operate an Airbnb listing, renting out the second bedroom of my primary residence (which I own). I recently opened an LLC for my other rental properties. With that, I have also opened up a checking account to pass through all of my rental income and mortgage payments, along with other payments.

Is there any reason why I shouldn't pass my Airbnb income and expenses through the same business bank account, even though the primary residence, of which I'm Airbnb-ing the second bedroom, is not owned by the LLC?

My goal with this is to keep all of my business income/expenses completely separate from my personal income/expenses.

Thanks,

Steve
