Quite the contrary, I see you have not read the whole thread...tax appeal work is fine provided it is purely an appraisal or purely an advocate. Checking errors on property cards, depreciation factors, GLA...is fine in the context of doing an appraisal. Testifying to your appraisal in tax court is fine. Where appraisers run into issues, is when they find errors in the property card, or depreciation factors...then later do an appraisal.
The beginning work of just checking for errors, pulling sales...etc is often looked at as advocacy work...to later do an appraisal report, would seem a conflict of interest. A fun question that tax attorneys like to say or assessors when later arguing about the appraisal...
"...so Kali the client initially contacted you about helping them with a tax appeal...yes that is correct...what did you do for them...well initially I observed the property and got a copy of the property card...were you doing an appraisal...no I was checking the card for factual errors in GLA, depreciation site size, site valuation...oh so you started looking for problems in the property card...no, just checking the facts...well it would seem that really they asked to look for problems, did they ask you to look at the assessed value too....yes, but that was a different assignment....really, was this when you were looking for factual errors or after...after...how soon after...immediately following the property card assignment...so let me get this straight you were looking for problems before when they hired you, you completed that assignment looking for problems then became unbiased when looking for sales...yes...wouldn't it seem odd that you initially were advocating for them in finding errors to reduce their property taxes, then you became an unbiased observer of the market, don't you stand to make more money in this business dealing if you write an appraisal too...yes...so you have incentive to maybe pick lower sales to make sure you get the assignment...no I am bound by USPAP that does not allow me...were you bound by USPAP when they initially hired you...no...were you not an appraiser then too...well yes...why not...because I was not doing....and on and on it goes
Carni USPAP is the minimum standard you perform work under, not the highest standard...I have not gotten to where I am doing the minimum. Stating that USPAP is the only threshold one should meet is counterproductive to our profession. Your clients success is going to be based on your relationships with assessors, ALJs, judges, attorneys. Your relationships with these people will be based on your reputation...which will be based on how you are perceived by people as being an advocate or unbiased. Its cold comfort to know you are right via USPAP...especially given appraisers are the only ones who read it. I'm sure your client will sleep better at night paying more in taxes, because you are right via USPAP.
