It's about time somebody woke up to this con game! School districts are the worst when it comes to grifting. Texas law defines that school districts must tax at a rate of $1 per $100 of property value, but can't exceed $1.17 per $100. They also have to have any increase above $1.04 be put to the voters. They know that any school tax increase will likely get shot down at the ballot box, so instead, they put put the heat on the local tax assessor to increase property appraisals. And, the Texas Education Agency is a willing accomplice to this shakedown.
Public schools economically gang rape the homeowners. Every year they want more and more. I can't believe these failed corrupt institutions only want more and more.
If you really want to find out who owns your home, even if you own it free and clear, stop paying them their rental taxes/fees.
