general adjustments to the comparables' sales prices

"Adjustments
Since no two properties are exactly alike, adjustments to the comparables' sales prices will be made to account for dissimilar features and other factors that would affect value, including:

Age and condition of buildings;
Date of sale, if economic changes occur between the date of sale of a comparable and the date of the appraisal;
Location, since similar properties might differ in price from neighborhood to neighborhood;
Physical features, including lot size, landscaping, type and quality of construction, number and type of rooms, square feet of living space and whether or not a property has hardwood floors, a garage, kitchen upgrades, a fireplace, a pool, central air, etc. and
Terms and conditions of sale, such as if a property's seller was under duress or if a property was sold between relatives (at a discounted price).
The market value estimate of the subject property will fall within the range formed by the adjusted sales prices of the comparables. Since some of the adjustments made to the sales prices of the comparables will be more subjective than others, <bold>weighted<bold> consideration is typically given to those comparables that had the least amount of adjustment."
