"Hi, this is (your name) with (your company name). I see that you're trying to sell you home on your own.
"Before you hit the delete button on this message I just wanted you to know that I'm a full time REALTOR who lists and sells homes in your neighborhood and I would like to help you reach your goals in selling your home.
"If there's anything I can do to help you please call me on my cell phone at 000-000-0000. I'm not a pushy salesperson...we'll just talk and see if there's anything I can do to help you reach your goals. Again my cell phone number is 000-000-0000. Take care and have a wonderful day."
