No LLC - mortgage payment fine print

[Phillip M.]

hey so - 

I turned my first SFH into a rental.. I'm not making leaps and bounds of money off it by any means but it's a start!

my question is - i'm going to be opening a business account to try to keep all funds separate.. but i'm not going to LLC it just yet..

wouldn't the fine print of the payments then be using a business account to fund a personal property? 

and that would also bring into question for me, what should i start putting on my business account for tax purposes? phone bill? property management payments? 

thank you guys for all the help!
