Broker lease commission seem fair?

[Andy Olsson]

Can anyone with experience with lease commissions for a NNN property give some advice here? We have a stand alone building in the Phoenix area, currently occupied by a national fast food chain but they are leaving this summer so we will have to find a new tenant. The broker we are in touch with listed a commission schedule of 6% of base rent for years 1-10, 3% years 11-15, 1.5% years 16-20.

Does this seem fair?

Thanks!
