Hi there. Taxes vary within zip codes usually because of MUD district values. Remember, the appraised value on a home is not the same as market value of the home. Taxes are based on the HCAD value. Assuming you are referencing a home with an appraised value of $280,000---multiply that by the 3.44-3.84 rate for Fall Creek or Canyon Gate. To further complicate the answer to your question, if your home is eligible for homestead exemption, the taxed values are lower. Ngray, a realtor can provide valuable information regarding property taxes in the communities that you are interested in.. Give me a call.
