Lowering Your Texas Property Taxes
You can fight your property tax evaluations using comparable sold data from your Realtor (because Texas is a non-disclosure state, you have to be a Realtor to get this information from the MLS). I have done this in the past with some success and have clients who have done the same.
You can also hire a company that does this professionally. This will save you time and energy and even though you will have to pay the attorneys/company who fights this for you, you may still come out ahead.
I have fought the numbers from the county personally and I have used outside legal services to fight for me--and in the end, the hired gun paid better dividends for me than doing this strictly on my own.
If you are considering fighting your taxes, I recommend considering a reputable firm to fight them for you.
