Tax appeal question in NJ

[Ned Micic]

Hello BP! I have a question in regards to tax appeals in NJ. I own a 2 family home under an LLC. Is it required for LLC owned properties to use an attorney? Also, must I get an appraiser to do an appraisal on my property or I can i just pull up comps to prove that my properties appraisal value is less? If possible I'd like to do as much as I can myself. I am a licensed realtor and have no problems findings comps in my area.
