Liz,
I always recommend interviewing more than one agent/agency to get as much information as you can about how they will service your listing. You want to sell your property, not just list it.
My name is Karen Tibbals and I am with Weichert Realtors-Joe Orr & Associates. We are the #1 real estate company in Tullahoma. Any one of our experienced agents would be happy to interview with you to show you what we could do for you. I am one of them.
Please check out my profile. I would be delighted to offer you my assistance in any way.
Good Luck!

We are full time dedicated agents and we will strive to make your real estate transaction as stress free as possible.

I do not work in your area but would be happy to refer you to a top REaltor to interview.
My best advice on options is to pick one that knows the market thoroughly and commits to get your home sold. They need to have a marketing plan that you can evaluate and determine if this person can really to the job.

For Sale By Owner with the MLS Realtor option. It's a bargain and your property would be desirable.

Another great source for quality agents in the area is through the Council of Residential Specialists.
