personal income or property's cash flow

Good evening, everyone. I have another question similar to the one I asked before. When I am going to buy a property, how important is my income if the property is going to be rented out? I want to buy a fourplex and live in one unit. Does the price of the property that I can access depend on my income? Is this different when I buy a commercial multifamily property, the bank looks at the cash flow generated by the property rather than my income in that scenario? Thank to you all, I am trying to clarify my doubts.
