What is the proper type of bank account to run my rental through?

[Michael Coritz]

Hey everyone - new investor with some basic questions. I know this probably sounds pretty elementary, thanks anyways!

I have one rental property that was purchased with a VA loan and was my primary residence for 15 months and is now a rental property. I currently am just renting at my new duty station. The lease I currently have with the tenants at my rental started on Aug. 31 and is a 12 month lease. I have a property management company running the property for me.

As far as having my accounts in order goes, does it make sense to set up a business account to run all the rental property transactions through even if it is just a single property (and no, I don't have it as part of an LLC)? Currently though everything is run through the management company portal and I just receive a monthly check like usual. Or does it make sense just to have a separate personal checking and savings strictly for the rental property?

Additionally, regardless of if the rent checks I get are coming to a personal or business account, should I be paying the actual mortgage payments with the account strictly for the house or with the current personal checking account I have been doing so for the past 15 months? Thanks!
