Sold: the person who said that really means, "I would love to sell at that price."  By simply saying "Sold" we know that the speaker is excited and pleased about the appraisal. The appraisal is good.

We won't get half that much:  The appraisal for the property is US$400,000, but the people in this discussion think that price is high. One of them says that he figures 300 is more likely. He/she means US$300,000. The next speaker thinks they will not get even half of that which is an amount less than US$150,000.

Comps:  When an appraiser calculates the value of a property, the appraiser will look at properties that are for sale or have sold recently and will compare the sales prices. The appraiser will have a list of similar properties and prices, and they are called "comps" because they are comparisons.

the usual:  The appraiser followed normal procedures to determine the value of the property.

let's go after him:  The person who said this wants to confront the appraiser. The person who said this is unhappy with the appraisal.
