Pricing a property can be very tricky and not an "exact science". The value of a property is what a buyer is willing to pay for it.
You might find one agent has a different opinion then another,based upon personal experience in your neighborhood
My advice is to call in two more Realtors and get their opinions. After three you should know about what the property can sell for. I would trust the working Agents and their opinions since they are working in the field every day, they will know the conditions of the sales as well as the prices.
If after your interviews you still believe you can get more, you could put the house on the market for a higher price then recommend for the first two weeks and see if there is any interest.
If there is no interest you will then have to drop the price, but that is not a very effective strategy for pricing and sometimes backfires resulting in a much lower price then anyone expected.
