The other state is not going to give you any ruling in writing, since the answer depends on your future actions, which they can't control or predict.
While you're correct that a primary consideration is length of time you stay at that owned residence vs your domicile vs other locations. There are many other factors also considered in determining if that owned house is no longer your domicile. Particularly if that house was your previous primary residence, you must go overboard demonstrating that you have severed all ties to that state, other than simple ownership of the property. In the laws eyes, your ongoing activities in that state are just as critical as your actions in Tx to set up a new domicile. things like employment, operating a business, banking, schools, voting, social clubs, government benefits, homestead status, correspondence, connections, credit card records, and others can be used in addition to days spent.
Many fulltimers own property, some like me have multiple properties in several states. The property ownership by itself is not an issue, it just means you need to be extra careful about all the other issues to avoid domicile conflicts. However, none of my properties are a previous primary residence, that's the situation that draws the most attention to your actions or lack of actions.
