Property taxes in Tarrant County, Fort Worth, are frozen once you reach 65 years old. I didn’t file for my tax exemption until I was 67 and they reimbursed me for the taxes I had already paid. On a 2000 square foot house I pay about $2000 a year in taxes.
I often joke that I sold a shack in Rhode Island, 1200 sq ft, and bought a mansion, 2000 sq ft and brand new, in Texas for half the price.
I pay almost 3 times that amount for a little over 2000 sq. ft. in Collin County.
Here, in the country north of Austin, TX, we pay about $1000 in property tax for every 100 sq ft.
