Typically speaking when I was actively selling property in Tucson the average rate was 6%. Some big companies (atleast big locally) charge up to 7%. Those companies always had the best advertising and such, and the sellers were normally willing to pay that extra percent. Generally the Buyers agent recieved 3% of total purchase price. With the economy the way it is its not uncommon to see 4% given to buyers agent as buyers agents are more likely to show and push the sale of a house since they will profit greater from this deal. (maybe unethical but true) 5% was out there just not as common. Also alot of companies offered to list the property on the MLS for a flat fee (anywhere from $299 to $1000) but they just simply list the property on the MLS and thats it, your on your own as far as advertising and such.
As far as the broker comission is generall 1/2 of the comission that the agent recieved, thus the agent and broker would each recieve 1.5%
My specific office in Tucson, Az was set up a little different, instead of splitting my portion of the comission with the company I paid a "desk fee" of $50 per month and paid $450 to the broker per deal and keep the rest, simple break down
$200,000 purchase price
$12,000 in comission paid ny sellers.
$6,000 to sellers agent
$6,000 to buyers agent
where as some agents would pay there Broker $3,000 I simply paid my $450 deal fee and pocketed the other $2550 some other brokers would of taken. Yet my brokers wernt of much support when you needed them.
Generally for a full service realtor I do not see you paying less than 5%, which would most likely break down to 3% to buyers agent and 2% for the sellers agent.
Im sure you could find 5% but sometimes it better to pay that extra percent and get the property sold faster and/or at a higher price.
