Online discount brokerage services
http://www.tenantwise.com/

Here's a site tenants have awaited and commercial real estate brokers have dreaded. It offers to broker real estate deals at a reduced commission rate. The tenant gets the 20% savings in most cases and can use the money to pay rent or fix up its offices. An easy-to-use online calculator figures the savings. For now, the site has only property listings in Manhattan. But plans are in the works to roll out the service to other cities soon. In the meantime, check out the tenant information on what to expect during lease negotiations.
