Grant/Valkaria is a quiet area but if your wife likes to be near shopping or museums and such, she'd have to drive north to Melbourne. I loved the Sebastian area and Indian River County but disliked that there was no decent shopping in Sebastian; only a Walmart and a few thrift stores. For shopping, one has to drive about 15 miles south to Vero or even farther north, to Melbourne. Traffic in Brevard county (Melbourne, Palm Bay area) is always horrible, no matter the time of day. Vero Beach is very nice but some communities are quite expensive and to find property of an acre or more (without being a gated or HOA community) you'd probably have to look in the western sections of the city, out near I-95.
