$300/mo is crazy for bike storage. I’d suggest popping it in a storage unit if costs are that high. Throughout college, I kept my XSR900 in a unit for like $75/mo MAX. Probably less, but it wasn’t significant enough to remember. Otherwise, some apartment complexes rent spaces for 150-200/mo.
I wouldn’t worry about mice outside as much as I would rust. My brother parks his 9T outside as his apartment complex only offers outside parking, and has noted a little bit of rust in random spots on his 2017 9T (PA-kept).
Overall, it’ll be alright. Throw a cover on and keep an eye on any rust that develops, but I don’t think a bike would be as attractive to mice as a car engine bay, for example.
