Texas Real Estate Laws

William Bronchick wrote an artice about big brother watching and the state specific laws to watch out for. In Texas he mentioned that there are laws concerning land contracts and lease options. Can anyone tell me what restrictions there are?

From what I can tell, it seems like the law in Texas requires that you have deed to the property before you can do anything with that property. Meaning that buying on land contract and lease optioning are forbidden because you never actually get the deed. Once you have the deed lease optioning and using land contracts to sale the property is fine.

I appreciate any insight.
