Union Pier Michigan is in two school districts, New Buffalo Township Schools and River Valley Schools.
The majority of Union Pier is in the New Buffalo School district. River Valley Schools serve the North Eastern areas of "Union Pier".
Regarding "Schools of Choice" in Michigan: This is a provision in Section 105 and 105c of the State School Aid Act . It doesn't guarantee that a student will be accepted in another school district though.

Unfortunately, there is not a basic answer to your question. Rents vary greatly depending on the time of year, location/distance to water, ect. Many homes are rented weekly in the summer months, then monthly in the off season.
If you want to email or call me with more information, I may be able to help you get a better idea.
