Joe is correct; comps are more of an art that a science. Some properties are quite easy and others can be very difficult. Here are some good comp parameters that will be appropriate for most properties;
YEARS
5 years newer, 5 years older. Home built in 1999, comps are from 1994 to 2004. If the property is older than 1970, I go 10 years older, 10 years newer
SIZE
200 Square feet higher and lower. 1,800sf, I run 1,600 to 2,000. If home is larger than 2,500 ft2 or smaller than 1,200 ft2, I just go with +/- 10%
COMPS (Solds)
I always go 6 months back, unless I can not get at least 3 solid Sold comps, then I go back 12 months
AREA
I always start with the same subdivision of the property , if not have enough properties I move the months sold to 12 months. If still not enough, revert back to 6 months and move out by map to ½ mile, then by ½ mile increments, till I get at least 3 solid Sold comps.
BEDROOMS AND BATHS
I try to keep with the same number of bedrooms and baths
GARAGE SPACES (I only enter this in on high end comps)
Keep with the same number of Garage Spaces
