For housing in Blacksburg, Virginia where the Virginia Tech main campus is located, try the following resources:
The Virginia Tech Off-Campus Housing Website: www.studentcenters.vt.edu/vtoch/rentals/ocp.htm. You must register in order to search for available housing, but registration is easy and free. Listings are updated often.
Craigslist: http://blacksburg.craigslist.org/hhh/. Craigslist is an online forum for buying and selling just about anything. It is a good place to look for apartments but you should wait until you arrive, see the apartment, and meet the landlord to enter into any apartment contracts.
