Getting a job with the intent to leave in 1 year a bad idea?

Happy new year to all.

It's time for a new job and an MBA. Many bigger banks such as Key Bank, MUFG, JPM, Morgan Stanely, Fifth-Third etc have tons of positions out of my state. Many smaller banks have positions more local (within a 6hr drive).My goal is to explore a bit more commercial banking while also preparing to apply for an MBA. Ideally, I'd either enjoy the new location and stay or be a good employee and get a letter of rec for my MBA. Admittedly, the expectation of the latter occuring might be setting myself up for failure since it relies on me relying on a set up that would allow me to receive a letter of rec.

If I manage to get a good rec and get accepted to a euro, or US, program then I'm goig to pack my shit up and move. Moving to the new work location and moving away for an MBA will be a big financial drain, but it won't matter if I get a good ROI from the MBA. There will also be the opportunity cost of paying someone else's mortgage until I settle down and buy  my own home.

TDLR; Best case scenarios: I like my job or it opens up a clear pathway without having to resort to these antics I'm writing about OR everything works out perfectly  with the MBA route and I leave after 12-16 months
