Based on your post date...you may still be researching the 'rental'.
If so, it sounds like you are a student...correct? Have you considered finding a roommate? Also consider posting on Craigslist in the rental section..'WANTED'. In advance, many landlords are pre shopping for correct rent values and you just may be seen.
Also consider the school calendar...you typically get the available rentals when the school calendar is slow...making more availability. Consider: Move in sooner and get a local part-time job.
