The Internet is Key in Marketing in this Computer Age - particularly if your target market is the College Community. Here in NYC, the best venues are Property/Managemt Company's Website and The New York Times - Real Estate Section (both online and print -- which can be Pricey). In addition, I have used Craig's List - however, in NYC they now charge Brokers for Posting Listings on the Site. However, you can give the listing to a Broker, who will Market the Property for you -- on their website and in their advertising in exchange for exclusivity of the listing and the collection of a Broker's Fee (in New York - the fee is paid by the Tenant) upon the Lanlord's acceptance and leasing of the tenant.
