Bret is right on, a "comp" is a comparable sale, just to add a bit.
Comps must be selected based on time of sale, location, style and comparability to the subject property, the subject property or "subject" is the one you are comparing the comps to.
An ideal comp is a sale within three months and within the same subdivision, or within 1 mile. You don't want all of your comps in the same subdivision, you may use 2 but the 3rd needs to be outside that subdivision so that price is not greatly influenced by one subdivision or say one builder.
If there are no comps that meet those requirements you move further away from the subject within a 2 mile radius, then 3 miles and so on. You may also look further back in time, to six months. Comps should be within 3 miles and within 6 months if possible. Usually going back to an older sale is better than considering a property further away, a sale 10 months ago would be better than a comp 5 miles away with all other things being equal.
You can find the way comps are viewed on the Appraisal Institute's web site.
As you'll see there, the appraisal methods used in the market with comps is a process of deducting or adding to a sale price of the comp based on how the subject compares to the sold comp. For example, the sold comp may have a single car garage, the subject has a double car, you add the value of the additional garage to the comp to bring that sold value up. If it were the other way around, you would deduct the value for the comp sale price. That garage might be worth $8,000 and you will see that in the market with comps sold or you may need experience in estimating such values. That's what the appraiser does. Just remember, never adjust the value on a subject property, adjustments are made to comps.
When I started, I parked my wagon and hitched up my horses at my appraiser's office in the buying process when I got a copy of the appraisal and took it to him. He explained what he did to get the value. The best way to understand an appraisal is look at one and ask questions.
You'll also see there are three approaches, the market described above, the income approach, based on income potential of the subject and the replacement approach, what it would cost to build the subject and then depreciate the improvements based on age and condition.
It's an art as much of a science, don't expect to nail a value on a subject, your goal is to get close. :)
