Budgeting owner occupied rentals

[Lance La Croix]

Hello! Being a personal finance coach, I am very experienced in writing and following budgets that have my best interests in mind. That being said, I am brand new to real estate and I am unsure the best way to manage the finances of our soon-to-be owner occupied duplex. Taxes, mortgage, and utilities are all part of our personal budget however, part of these expenses will be covered by the tenants rent. 

Generally, when coaching a business owner, I advise them to have 100% separation between business and personal finances. How does one do that if they are living in their business? 

Any words of wisdom would be appreciated!
