How to separate personal and business expenses

[Frankie Betancourt]

Hello I recently Quit my Job to Rehab properties Full time but always had One Personal checking account where all my rental income goes into  about 6k a month i collect cash (easier for me and tenants) But how does one do this  i had planned on opening a separate personal account only where i deposit Rental income into but if i do So How will i Pay for modern day living expenses food,bills,car insurance,phone, etc...If ALL my income is going into the business account? because i dont want to  MIX the two for tax purposes and how do i know what is considered a BUISNESS  expense related transaction when i charge my buisness account?
