You need to run the net price calculator for any schools of interest. Google school name + NPC and use the one on the school website, not a third party site.
Why are you only considering public universities? Many state schools exclude OOS students from need-based aid and may limit merit. For example, you are interested in CA schools but they don’t give aid to OOS students so your cost will be about $75k.
Start with the NPCs and remove any unaffordable schools. Your state and any nearby states with reciprocity should meet budget.
You may get some good information from this thread. Best of luck!
