While this may be a viable strategy in many states, please be aware of the following part of the Property Tax Code in Texas;
Subchapter A. Tax Sales
Section 34.04 Claims for Excess Proceeds
(i) A fee charged by an attorney to obtain excess proceeds for an owner may not be greater than 25 percent of the amount obtained or $1,000, whichever is less. A person who is not an attorney may not charge a fee to obtain excess proceeds for an owner.
