The "Home Ownership Matters" bus has parked at the Rotary Fountain Plaza in Riverfront Park.
The bus, a project of the National Association of Realtors, is promoting the benefits of owning a home during one of the most challenging periods for the industry in decades.
Spokane is the only Washington stop on the bus tour. Portland is also on the schedule.
The NAR says home sales generate 2.5 million jobs in an average year. Subsequent sales of furniture and other improvements add $60,000 to the economy.
The Spokane Associaton of Realtors marks its 100th anniversary this year, and members will be gathering at the bus for a group photograph.
The local association has 1,500 individual members.
The bus was scheduled to depart at 3 p.m.
