Once your house is in the MLS, your maximum exposure is going to be
3%. Of course, you can specify in your MLS listing that you will pay
2% or 1% or even 0% buyer's agent commission, but then no realtor will
show your house to their client!

2% buyer's agent commissions are quite common, and there are plenty of
agents that are quite happy with their 50% cut of the 1%. On a 1,000,000
house this is still $10,000. Some brokers forbid their agents from
showing houses that don't have the "full" commission, the legality of
which is questionable.
