Apartment searching

When do I start the searching and touring for a new apartment? I move out of my current ones in September but we plan on staying with our parents a month after before we get back out there to save. I do want to do a lot of research before we do because I want to guarantee that our next apartment we won’t have to move and at least get a couple years in to save some more before we move to a house. We moved into our current apartment too fast before we even did any research and I was ready to move after a month I want to be sure that doesn’t happen again. 😅
