personal or business account for misc expenses

[Jeremy Sharp]

hey hey...I own a duplex in cincinnati that is currently being managed under a property management company (while my wife and I lived in Japan and now have since relocated to Lexington). The house is set up under it's own LLC already but since it's under a property manager, they already have their own bank account for the day to day activities (rent, repairs on the house, etc). I don't have a debit card, etc to access this account.

As you know there are other misc expenses outside of the house. I.e. buying a computer, lawn equipment, seminars, gifts, etc that would be a general expense that I would buy and not the property manager. 

My question is how do you suggest managing the bank accounts?

1. get access to the property manager's account (which adds confusion, etc)

2. get an additional business account under the LLC name

OR

3. an additional personal checking account just for the misc expenses

I am torn between a business account or personal checking so would love to hear your thoughts!
