My comment: AMCs seem to be assuming that tax records are more reliable than appraisers’ measurements. WRONG!! I started appraising at an assessor’s office in 1975. We were no more accurate than any other appraisers and never thought that our square footages were exact.
I used to do a lot of relocation appraisals where 2 or 3 appraisers were hired to appraise the same property. Very, very seldom did the appraisers have the same square footage.
A few years ago, a local real estate agent asked me about an appraisal where the sketch did not match the house. Tax records sq.ft. was way off. The appraiser had “fudged” the dimensions to match public records.
Do many appraisers do this to avoid AMC hassles or they were taught to do this by their supervisors?
I have always looked at tax records sq.ft. as a cross-check, but never assumed it was more accurate than my measured sq.ft. In some neighborhoods and cities, they are accurate and are very unreliable in other areas as they often are not correct.
9/20 update. Not much has changed. Still a big problem!!
