Please do not shop by commission. A REaltor may charge a very large fee, but have such a well-developed marketing plan, that he/she is able to get a much higher sales price than an agent who may do no more than place the listing on the Multiple LIsting Service.
It is important to determine competency, experience, ability to negotiate, integrity and see a written marketing plan of what will be done besides listing on MLS.
There is no law that sets or mandates commission percentages. The law does state that Realtors can not discuss commission on open forums like this as it can be considered a violation of the antitrust act. So no one can or should be stating any commissions. You really need to call some companies and ask what they charge. THE MOST IMPORTANT THING is what do you get for that commission, low cost or discount brokers charge less but you get what you pay for. Full service brokers can have lower costs or be independant and not have to pass franchise fees onto you. You should be able to get your house advertised each and every week, you should get a marketing plan and the broker should be willing to do assisted showings on your property instead of installing a locbox and sending people unassisted by your listing agent. Good luck with your sale
If they come in and quote you the lowest fee right off the bat - well than they're not good negotiators (you know this because they didn't even try to get a good price - how respectable is that?) and they're also desperate.
I walk from listings where:
1. I don't believe will sell at the price the homeowner "must have"
2. The seller(s) don't want to pay a respectable fee for my services
3. The sellers motivation for selling is low.
I qualify homesellers for my services as much as they qualify me to sell their property.
