The 1004 form is asking for the quality of construction. .
Fair quality of construction compared to a neighborhood of fair quality construction with an active market of sales should be acceptable to a lender because it demonstrates marketability and market acceptance.
Fair only becomes a problem when the subject is in a non-homogeneous neighborhood and sales of fair quality are well below the average price for the neighborhood.
I agree with Randolph. However, most appraisers do not have the experience or background to determine "fair as opposed to average quality." Furthermore, what distinguishes "fair" is typically inside the walls, inside the materials and is often exacerbated by poor workmanship. That said, I have often seen excellent quality but put together with poor workmanship. What many appraisers might do is to equate CONDITION to QUALITY. If it meets local codes, it is more than likely Average or better quality. Lumber, for example, to meet local codes must be rated standard or better and it is stamped on each board. ALL approved materials are rated by ICBM (International Congress of Building Materials inspectors). Concrete is required to be of a certain mixture ratio.....on and on. So, unless you can PROVE that inferior materials were used throughout the building, do not place a FAIR tag on it. And, yes, you can be sued for mis-identifying the rating.
