I have yet to protest my taxes yet (stupidity on my part), so this year would be the first for me. Some of this information I got from talking to other realtors, investor, instructors and the like. I can't vouch to say that any of this works, but it's definitely something I will try this year and would like to hear if others have success in doing so as well. Unfortunately, this would only apply to Texas because of the State Property Tax Code. But I would encourage others to find something similar in other states.
1. Submit written notice at least 14 days prior to your hearing requesting what evidence the appraiser will be using to determine your property assessment value. Referencing the Property Tax Code-
Sec. 41.461. NOTICE OF CERTAIN MATTERS BEFORE HEARING.
(a) At least 14 days before a hearing on a protest, the chief appraiser shall:
...
(2) inform the property owner that the owner or the agent of the owner may inspect and may obtain a copy of the data, schedules, formulas, and all other information the chief appraiser plans to introduce at the hearing to establish any matter at issue; and
The advantage for property owners is that they can know in advance what data (e.g. comps) the appraiser used or plan to use to calculate your assessment value at the hearing. But it doesn't stop there.
Sec. 41.67. EVIDENCE.
(d) Information that was previously requested under Section 41.461 by the protesting party that was not made available to the protesting party at least 14 days before the scheduled or postponed hearing may not be used as evidence in the hearing.
What I understand this to mean is that in your hearing the appraisers can ONLY use the data/comps that the appraiser already provided to you.
2. Unless if I'm reading this wrong, foreclosures cannot be excluded from determining property assessment values according to the Texas Property Tax Code.
Sec. 23.01. APPRAISALS GENERALLY.
...
(c) Notwithstanding Section 1.04(7)(C), in determining the market value of a residence homestead, the chief appraiser may not exclude from consideration the value of other residential property that is in the same neighborhood as the residence homestead being appraised and would otherwise be considered in appraising the residence homestead because the other residential property:
(1) was sold at a foreclosure sale conducted in any of the three years preceding the tax year in which the residence homestead is being appraised and was comparable at the time of sale based on relevant characteristics with other residence homesteads in the same neighborhood; or
(2) has a market value that has declined because of a declining economy.
I plan to literally print this section of the tax code and bring it to my hearing in case if the appraiser excludes any of my comps that are foreclosures.
3. From what I heard when you protest your property taxes you're given a scheduled date/time for your hearing. In some cases the hearing can be in front of a panel of several or just one. However, I've heard others say that you can walk-in any day/time before your formal hearing and request an informal hearing the day of. The advantage of this is that you catch the appraisers off guard so to speak or give them limited time to prepare for your case.
Again, I haven't tried this myself since this would be the first year I will be protesting my taxes. But would like to hear if others have any success in the above.
