Grapevine is a suburb of both Dallas and Fort Worth. Though our current home is in Austin, the capital of the state of Texas (we relocated because of employment), Grapevine is given consideration as a place we could spend our golden years, i.e. it's in our retirement planning goals.
Texas has a GO TEXAN Certified Retirement Community Program. Cities apply to participate and go through a rigorous approval process. If they pass the tests (safety standards, healthcare, etc.,), the Texas Department of Agriculture certifies that city as a great place for retirees. So far there are 45 cities with this type of designation. But keep an eye on Grapevine. The city is not in this program yet. But by the time my spouse and I retire, it might be. There's no reason why not! (My humble opinion.)
Here's some scant information about Grapevine. But it's enough to decide whether or not it's a great place to live and work, or retire.
