It's simple and it's in writing.  I am so confident you will be happy with the services I provide, I offer the following guarantee to all my home selling clients:

 

When you list your home with me, if you are not satisfied with

the job I am doing for you to sell your home, you have the option to cancel our agreement at any time, for any reason, at no cost

or with any further obligation.  

 

Don't get stuck with a long term listing agreement.  When you list your home with me, it's like having a 24 hour listing agreement.   It's just that I don't make you sign it again every day.
