It is the quality of the measurements of the comparable sales that determines the needed quality of the measurements of the subject when doing an appraisal. Suppose you measure the subject an find it is 2326 sqft, but public records indicate 2500 sqft. You have 6 model match sales by the same builder, similar lots, classic cookie cutter houses. Every record you find for the comparable sales says 2500 sqft. Has measuring the house added anything to the cedibility of the opinon of value? Would it be most prudent to:
- use the measured value for the subject and all comparable sales,
- use the measured value for the subject and public records for the comparable sales,
- use the public records for the subject and all comparable sales?
Now add a sale in the same neighborhood by the same builder with one less bedroom and public records indicating a size of 2350.

I would indicate 2326 for the subject and all comps in the subject neighborhood that show the same floor plan as the subject, disclose the discrepancy, disclose why I modified the comps GLA figures and write an EA/LC to cover my back-side if it turns out I am wrong.
Relative to the comp with one bedrooms less, it could be that it actually is 2350, with the area from one of the bedrooms used for something else. I would try to determine one way or the other the likelihood of accuracy vs. an actual discrepancy similar to that affecting the subject. I I can't determine for sure, then I go with PR... and I disclose that too.

Is in not obvious that the measurement of the subject, although nice information, is irrelevant to the appraisal?

WHAT???!!:Eyecrazy: you need to come back to Florida... The slightly drier air up there is causing your brain to chap, I think.

If solid numbers were known for the comparable sales, would not the relevance of the measurement of the subject property to the appraisal process be increased?
In either case I would want to have measured and explained any significant discrepancy in my report between the public records and my measurements. Measuring is a good thing to do, but certainly not a necessity IMHO.
The purpose of measuring, IM<STRONG>O is not to simply note the discrepancy relevant to public records. Just because we are forced to deal with a certain level of inaccuracy in the comparable data is no reason to throw your hands up and simply say it doesn't matter to what you're doing. You are completely missing the point.
If you have two mating parts of a machine, the more slop, or tolerance you alow in each part increases the chance that it will not work properly. If you can't get both parts made perfectly to size, then getting one part right will decrease the number of failures you have. Its the same principle with information based comparisons; less inaccuracy, even if just on one side of the information being compared, makes for a more reliable analyiss, and one that the Client can have more confidence in.
BTW, for most homes around here, if public records is wrong, it will typically be on the low side, because if it's high, homeowners will straighten out the County appraiser yesterday in order to keep their assessment down. If it's the other way around, the homeowner will take that little secret only to his grave.... or the Realtor he lists the house with
