A new Web site for leasing office space aimed at commercial tenants and landlords rather than brokers and agents has been launched.

TenantWise.com provides information and resources to search, negotiate and finalize leases for office space. The site features listings of available space, bidding calculators and recent taking terms of leasing transactions, as well as live-person assistance and advice. Also available are brokers to assist companies through the leasing process and listings of goods and service providers.

The site is being marketed as the rare commercial real estate site that's not broker-centric. Rather, TenantWise.com provides information for commercial tenants to “take greater control of the occupancy process,” the company said. It also allows landlords to list properties free of charge.

The site hopes to draw users by offering commission savings to tenants and landlords during transaction time. For example, a tenant leasing 10,000 square feet of space could save $40,000 by using the site in a typical transaction, the company said.

The service is currently available in Manhattan and will soon be rolled out to office markets across the country.
