The defining characteristic of a drive-by appraisal is that the appraiser doesn’t go inside the
house. The appraiser merely goes out to look at the property — “drives by it,” in other words —
to take pictures and verify that the subject property physically exists. The overall condition of
the subject is usually assumed average and was influenced by quality of the exterior and
information provided by owner. Assumptions are made based on this information and are taken
into consideration in determining overall condition and value. The rest of the appraiser’s work is
done with real estate records — analyzing assessments on the home and neighboring properties
and looking at recent sales of comparable homes to arrive at an estimate of value for the subject
property.
