Approving for loans with my business income

I have a personal and a business account. I only use my business account for my 3 rentals I own. So I know what money is coming in and out. But when I go to get approved for a loan they want to see my business income. I also do other jobs that money I put in my personal. Should I start putting all my money I make in the business account? It would double my income. Or would they need proof it's income from my real estate business?
