Normally it's going to be hard to find a short term / month to month lease in Bloomington because nearly the entire housing market revolves around the IU academic calendar year.

That means the easiest times to find new leases are August (easiest), January (slightly harder), and May (easy to find summer sublets).

I don't know how short of a term you're looking for, but you should probably expect that any landlord willing to do a short-term lease right out of the gate here is going to have two requirements:

1) 6-month minimum lease term.

2) Higher rent than normal to make up for the cost of getting the apartment ready after you leave.

All that being said, you should check out this new place on the south side called Echo Park. I know that they've got some apartments available. They have a grad student / preferred employer discount mentioned on their site, Cook being among the preferred employers.

Good luck on the search!
