Beginning September 1, the revised version of the TAR Seller's Disclosure Notice (Form 1406) must be used. The new version includes entries for a "single blockable main drain in pool/hot tub/spa" and the definition of "any rainwater harvesting system connected to the property's public water supply." It also specifies whether any liquid propane gas is "community (captive)" or "on property." The revised form is available from zipForm and TexasRealtors.com.
