I am sure by now you have all your answers! I am just wondering why NOW, it seems that you have worked with this particular Realtor for almost 2 years and now you want to get out before the last 4 months, what has changed?
As far as pricing goes, sit down with her and have her present to you current competing homes, even go and look at a few of them with her, then let her show you what homes at what price similar to your home or to your current price have recently sold..... You will then be well informed!
It may be your home, its size, location, age, updates or floor plan, or it may be the current asking price...
Discuss with her, now that she has put in so much time and effort, what TOGETHER you can change...
May be you take the suggestion of doing some up to date color painting, even if only one wall in certain rooms or a hallway etc. have the agent take new photos, may be get a staging professional to come in and
help you and your Realtor to move around some furniture, or even remove some furniture.... Curb appeal etc.
Remember in reality you and your Agent are in this "Boat" together, she as much as YOU are interested in selling the home, remember she does not get paid anything until and when your home closes, all her time and expenses come out of her pocket until.....
So try to work it out, it seems to me, that a feeling of desperation, makes you think that another agent will do
better or will do "miracles", if the new agent will come in and suggests painting, staging, curb appeal changes, even some minor repairs and then YOU MUST LOWER THE PRICE to get offers...... YOU MAY AS WELL DO T H A T with your current Agent, you obviously trusted to higher in the first place.
But to answer your legal concern, all the other agents below have given you the information you need, so I do not want to repeat.
Good Luck to you and I hope you can work it out, and get your home sold, It is a difficult market because of the economy, and in most parts of the country if not all we are in a buyers market, i.e. there are more homes available than there are ready and willing buyers, so good times for buyers, not so good for sellers.
