Dexter,

Realtors generally know more than the value of a house than appraisers do, actually. It's really all based on "comps" which is the selling prices of other similar properties in the area, and realtors are very familiar with that. The realtor often send the comps to the appraiser to establish the price they have set.

That said, realtors will set the price as high as they think the property is worth or could sell for, with the understanding that buyers will often make a lower offer and want to negotiate. So, you could get what the realtor tells you the house is worth, and you can hold out for that, but you can also negotiate down as far as you are willing to go. All the offers go to you to accept or decline. Unless there is something seriously wrong with the property, you'll probably get offers that are reasonably close to your asking price.

Realtors probably won't set the price unreasonably high, because if you can't get an appraisal for the price you and the buyer agree on, the sale could fall through, and they don't want that.
