If I may, to add to the important considerations Charles has listed...
Make sure the local grocery offers motorized shopping carts, they're not just for fat asses, wheezers can use them too. And inquire if they have an aisle dedicated to soft, easy to chew food. Don't overlook Gerbers, which you can tell the checkout is for your grand kid. Make sure the new home has at least one wall mounted defibrillator plus windows that open easily for screaming to the neighbors for help. Check that the local police firstly exist, and that they have a unit to deal with home invaders who most commonly choose the over-60s as their prey. The lawn and garden center can sell you varmint poisoning which you can also use to deep six any neighborhood cat or dog for crapping all over your driveway, or just for the fun of it. Have MAGA lawn signs handy for immediately implanting come the fall, they'll get you horn beeps and thumbs up from passersby even if you may not be of that particular faith. Most importantly, keep the house well stocked with dried beans and canned comestibles, for use while living in the basement, either during hurricane season or for when Macron starts bombing, for we all know the French can't be trusted.
