Mortgage Anti-Deficiency protection can be waived.

Although Texas has a statute (Tex Prop. Code §§ 51.003-51.005) that protects against deficiency liability in certain circumstances, it also provides that the protections of the statute can be waived by non-individual (non-consumer) borrowers. Grace Interest LLC v. Wallis State Bank, 431 S.W.3d 110 (Tex. App.-Houston [14th Dist.] 2013) confirms that such a waiver can be given effect.
