Homestead exemptions remove part of your home's value from taxation, so they lower your taxes. For example, your home is appraised at $100,000, and you qualify for a $25,000 exemption (this is the amount mandated for school districts), you will pay school taxes on the home as if it was worth only $75,000. You can only claim homestead on ONE property. It has to be the one you reside in, not investment or second home.
