An appraiser used auction comp to come up with value for our home we are selling. There were plenty of other comps available and this comp brought the price way down (15000 less). My question is: is this ethical, and if there are no restrictions on doing this, would it not be the same as using a foreclosed property? These types of properties sell for way less than a 'normal' sale and bring the comps way down. What are your thoughts? Thanks
