A comparable property sold one month ago for $400,000. That property has a three-car garage, whereas the subject property you're preparing to list only has a two-car garage.

What should you do to determine the subject property's market value?

The use of comparable analysis in real estate considers value of all components of comparable properties, and estimate price based on sum of features of each property.

So for the $400,000 property that has 3 car garage, we will need to find out the value of one garage.

Then since the garage size is the only difference between the two properties, adjust price downwards by deducting the value of one garage.
