Architecture’s a tough nut to crack financially. As @NewJersey17 noted, not all State U’s are low cost – or even offer the BArch for that matter. If your family doesn’t have adequate savings or qualify for need based aid, or if your high school performance doesn’t merit merit aid, then you really have no choice but to borrow if you want to practice architecture, either with an undergraduate degree or the MArch. Schools with co-op programs offer some respite, but often not enough to graduate debt-free.
It’s a dilemma.
