Protest Your Taxes!
Property taxes in Texas are high! For this reason you should always protest them.
It doesn't cost you anything and you can even use an attorney for no upfront cost many times. If you hire an attorney like Texas Pro Tax they only charge when they're successful. Typically in the amount of 30-40% of the savings they get you. So if they save you $3000 in tax, you would only pay $1200.
Why should you care about lowering your taxes if you're selling your house? Because the buyers do.
A house with lower taxes is extremely attractive to buyers because it affects their monthly payment. Additionally, because buyers are qualified based on what sort of monthly payment they can afford this reduction in taxes can allow them to pay more for your house!
So go protest your taxes! You could save a lot of money and also sell your home for more!
