When should I apply for transfer admission?

So I’m thinking about transferring from my community college to a 4-year once I reach 30 credits, the number required by the school’s I’d like to go to to apply without high school or SAT grades. I will be taking 9 credits over this summer and then I’ll only need to take one more class in September to reach 30.

The school has an October 1 deadline for transfers to apply for spring admission. So when should I apply? I know it differs from school to school, but generally speaking can you apply before you’ve actually completed all your courses?

Usually it depends on the school. If you’re in California, most universities only accept upper division transfer students; that is, students who have completed 60units at their community college. You’d have to look into the policy of whatever school you’re applying to. It also depends on your intended major. You’ll have a better shot of getting accepted if you complete all your GE’s and low division major requirements (which can be found on assist.org)
