As you heard from the previous answers, this is a program by which a Realtor tries to get your listing and if it does not sell, they "guarantee" to purchase it at a very low price, usually about $.60-.70 on the dollar!! It is not really practical... it is more of a gimmick than anything.
If you do not have your house listed yet, I am a Residential Specialist and have an excellent track record of selling homes for what they're actually worth in a shorter than average amount of time. I use a very extensive marketing program, over 20 years of sales experience, and no gimmicks or questionable methods.
Feel free to click on my photo, review my Credentials and Client Testimonials, and contact me ASAP if you have not yet signed up with another Realtor. Thanks, Joe Jarusinsky, Realtor/Master Instructor, Keller Williams Realty, 512-261-4415
