IU departments do not arrange housing for visiting scholars. It is necessary for each scholar to make his or her own living arrangements. Indiana University offers a variety of housing options on campus. See the housing application and costs at the website of IU Division of Residential Programs and Services. Prices are provided for full semesters. If an apartment is available earlier than the start of semester, you will pay a daily rate for the extra days.
On-campus housing is not always the most affordable option, but it does have the advantage of advance reservation and includes utilities, internet, and television cable service. Local telephone service is also included, but you must provide your own telephone. Residence halls (dormitories instead of apartments) require purchase of a meal plan. Mandatory meal plans tend to be expensive; ask for prices before applying.
There are a few on-campus apartments that are completely outfitted with furniture, linens, and kitchen utensils. Other on-campus apartments are unfurnished (completely empty except for a stove, refrigerator, and window coverings).
Many short-term visiting scholars prefer off-campus housing and find apartments or boarding rooms after arrival in Bloomington. Off-campus apartment hunting may be difficult at certain times of the year. Immediate housing is most readily available in May and August. Most property owners expect a one year lease (an agreement to occupy and pay monthly rent for 12 months). There are fewer options for scholars who stay less than twelve months, but housing is available.
For hotel information, review the Visit Bloomington website. It may be difficult to reserve a hotel room at the start of the school year and during football or basketball weekends.
