You've put a fresh coat of paint on the walls, decluttered the closets, and spruced up the yard. The only remaining hurdle before you put your home on the market will be to decide asking price with your agent. The key might be to think like a retailer.
Merchants understand better than anyone how buyers perceive value. And there's a ton of evidence to prove that retail strategies pay off.
Round numbers, such as $290,000, convey an image of quality and prestige, but they may also be interpreted by buyers as inflexible pricing. On the other hand, an exact figure such as $289,863 makes a buyer think "deal". If you're after a quick sale, go with the unique price.
If the competition is fierce in your area, you may also want to consider borrowing the retailer's "loss-leader" tactic (offering a desirable item at a very low price or at a loss for the purpose of attracting buyers). Putting in new sod and a backyard firepit may not boost your asking price, but it may very well get buyers through the door, the first goal of any successful sale.
