I think that discount agencies are wonderful. They offer a mid-range service for those who are doing exactly what you're talking about, Dawn, trying to save a little money, and are willing to pick pick up the slack for the marketing work that's required to get your home sold.
If you feel comfortable handling the LISTING side of the work, and have done this before I think it's terrific, and a good option (here come the thumbs down... but hold off a moment, okay?), but the option isn't for everyone. If, as Ruth suggests, this is your first home to sell, and you haven't been down this road before, you may be doing yourself more harm than good. Today's market, as you know, it a tough one, and it requires the utmost in marketing skills. Good photographs, quality descriptions, 4-color flyers and brochures delivered to all the local agents who are carrying the buyers who are looking for properties like yours, the occasional well-placed print ad, coordinated follow-up calling to the agents who's shown the property for feedback, etc... If you feel comfortable handling that, as well as handling appointments for showings, setting up the lockbox, etc... then a company like Help-U-Sell, or any of a myriad of discount listers, would be great.
If you're not up to that challenge, I'd suggest that instead of offering a bonus to the buyer's agent (who is NOT the person buying your home) spend the extra money by hiring a decent listing agent. I'm not sure what rates agents in Henderson are charging these days, but I'd guess that if you were willing to pay 5% (1% more than you're offering in your scenario), you'd be able to find a quality listing agent in your area, to handle every aspect of your listing. For that extra 1%, you'll get his/her expertise in your market, and have all that extra time to make sure your home is in ready-to-show condition at all times, so that when your new agent does manage to attract that buyer, the home shows at it's best.
Just a thought.
