to contribute to a SEP IRA you need earned income - income subject to self-employment tax. Schedule E rental property income is not SE income and dies not qualify for SEP-IRA contribution. Your consulting business would generate self-employment income so you can make the maximum contribution allowed based on it's income. as to number of a/c's, there is no limit. you could have one with bank A a second with broker B and so on. the only limit is on what you can contribute.
