Hi Dan and Carol,
There are some Ranch Homes in Hemingway that have fences, I don't know if there are any new ones for sale with fences or if you would be limited to a resale. We and several of our neighbors have Invisible Fencing in TV and it works great for us and them. We love the freedom it provides us and our girls, of course we never leave them out unattended.
Good luck with the house hunting.
