1 bank account for all properties or 1 bank account for 1 propert

[Account Closed]

So I currently have one property and pay for everything for that property on a specific debit card or checking account associated with all the repairs and maintenance ect.

I was taking to my brother in law who's a financial advisor and he thinks it's best to have all the properties under one account, he says, "as long as it's being tracked on paper you'll know what's your money is going". I think it makes more sense for my next property to structure it as follows

-Make an LLC

-Make business account for that LLC (get all the startup benifits of opening a business account with a big bank).

-Purchase house personal account then transfer property to llc.

-Pay all bills with associated credit and debit cards linked to the LLC.

Is this a good way to structure my real estate finances? I'm open to hearing what all of you are doing and how I can improve.

I'm also thinking about adding in a property management LLC but I'm not sure where that would fit into the equation.
