I had no idea my home was over-assessed by nearly $40,000. County Tax Appeal handled everything — I didn't have to attend a single hearing. My tax bill dropped by over $1,200 the very next year.
As a condo owner, I thought appeals were only for big commercial properties. CTA proved me wrong — they reduced my assessment significantly and the whole process took about 3 months.
