Your original goal was to list at $149,000. You listed at $172,000. That is about 15% above your intended price. That is 6% above the 'absolute silence' threshold. Clearly you need no additional advise. That, however, does not mean I am done.
Be aware, only a willing buyer and a willing seller will reach an agreement on the purchase and sell of a home. My impression is you have experience in the real estate business and understand your margins as well as strategic value.
You may be well advised to review with your agent at least three strategies to get this house sold. If all that is offered ONLY involves lowering the price, you are then in a difficult position.
At this point you will need to rely on YOUR negotiation skills and your apparent understanding of your local market. If your home is indeed 'The Prom Queen' of all the comparable real estate, you can make that work to your advantage. Employ denial strategies to get all those buyer in the house TOGETHER! You'll know what to do from there. (Read Ron's paragraph 3)
Best of success in achieving your selling objective.
