Yes, you can cancel with no fee, and list with another REALTOR®.
Not only are we REALTORS®, we are state licensed Real Estate Brokers. It takes many classroom hours and years of experience to become a broker. Being a broker, you can own your company and sponsor other agents. 
* All listings look the same on the MLS (Multiple Listing Service). We get a lot of clients that were listed with 6% agents, cancel with them and list with us. We even get a lot of agents listing with us because their brokerage will not give them a discount on their personal homes.
If you have ever listed on the MLS, then you have listed this way. 
Sometimes sellers think they are doing something different, but this is not the case.
We are listing on the same local MLS as any other agent, but instead of charging a 3% commission at closing we are charging you a low flat fee,
We have "unbundled" our services. You pay for the service that fits your needs. We are your listing agent. Your listing will look the same, as all other listings. How much you pay us to list is not mentioned on the MLS. The only commission listed on the MLS, is how much you are offering to pay the buyer or leasing agent.
You are not listing your property yourself.
No, we are your listing agent, but instead of working for a high commission, we are working for a flat fee. We provide all the same services as any agent. There is only one REALTOR® MLS in your area, and this is where we will be listing your property.
Depending on the listing package, we can help you with pricing, contract review and contract negotiations. We are full service agents. We have done traditional 6% real estate in the past, but do it this way, because it is a fantastic service.

We  are your listing agent, however if a buyer comes to you directly as a FSBO - FOR SALE BY OWNER you can sell to them and not pay a buyer agent commission, but we are still your listing agent and still here to help you with the process (depending on listing package).
Our success rate is 100% when clients listen to our advice.
We have been doing this for many years and provide you all the tools for a successful sell, but ultimately the sell of your property depends on what you do. If you overprice your property, there is no magic any agent can do.
Yes, agents will show your listing. You are not a "flat fee or fsbo" listing on the MLS. All listings look the same.
We have been doing this many years and sold thousands and thousands of properties. The only commission agents care about is theirs. How much they are offered is posted on the MLS. The listing agent commission is not posted on the MLS. You decide how much you are going to offer the buyer's agent. You are not a FSBO on the MLS. Your listing looks just like all other listings.
