International student lease timing

I got accepted to the PhD program for Fall 2024 and heard that most likely would have to live off campus.

I wanted to know typically when do people lease apartments. Do you have to sign up for some kind of wait-list early or can you get a lease during/after summer.

Also would love suggestions, for places to look for. Like I heard Rustic is economical but there are transportation issues. Whereas Apex is expensive but closer.

Would appreciate any help.

Tldr; when should u lease off campus for Fall as an international student.
