Texas Property Tax Protest

[Victor Williams Jr.]

Good Morning BiggerPockets family!

Quick question:

I own a property in the Valley Ranch area of Irving, Texas.  At least once a year I get a letter in the mail about considering protesting the property tax amount that's being paid.  Is this just a scam where this organization gets money for "taking my case" or have any of you ever been successful in substantially reducing property taxes by petitioning the state assessor?

Thanks in advance for your input!
