Real Estate MathIntermediateNorth Carolina Exam

An appraiser uses a comp that sold for $320,000. The comp has a pool (value +$8,000) but lacks a garage (value -$12,000) compared to the subject. The adjusted comp value is:

A$316,000
B$324,000Correct
C$300,000
D$328,000

Why $324,000 Is Correct

Answer B: $324,000

The appraiser adjusts the comparable to match the subject. The comp has a pool the subject lacks, so subtract $8,000. The comp has no garage, which the subject has, so add $12,000. Adjusted value = $320,000 - $8,000 + $12,000 = $324,000. Fannie Mae's guide says adjustments reflect the market's reaction to differences between the properties and are applied to the comparable sale price.
