The 5-year B-Arch at Virginia Tech includes (at an additional cost) a study abroad which is typically done during fall of the 4th year, so that should be factored into overall cost (not sure if it’s mandatory or optional). Also, studio and supply fees for Arch programs can be steep so I would look into those at all the universities you’re considering.
B-Arch programs are competitive admits. Depending on how much weight each program places on your SAT vs. your class rank/GPA (and taking UT Austin out of the picture), VT, Auburn, NC State and possibly also UTK will likely be reaches for that particular program.
