Norman, I noticed you haven't closed out your question. I wondered if you found what you were looking for and if you are still happy there. As far as single Family Home Senior Communities in Katy are concerned, Heritage Grand Cinco Ranch is still the extent of selection. If at any point you would like to explore other areas outside of Katy, or other communities outside the realm of Senior Communities, please feel free to reach out to me @ 832-373-9755 or cody@interohouston.com.
In Cinco Ranch there is the neighborhood called Heritage Grand, for residents over 55. It's very nice. I live in Cinco Ranch, since '97, about a mile from Heritage Grand. When your are available to tour the community and receive more detailed information let me know, I'm happy to assist you.
