With timelines uncertain for returning to school and offices, many vacation-home buyers are seeking out properties that can double as full-time homes if necessary. Atlanta residents Tyler Scriven and his wife Faith McCoy Scriven were already in the process of looking for a weekend home when the pandemic hit. They had decided on the wellness community of SErenbe about 45 minutes outside Atlanta, Mr. Scriven said, and had their eye on an under-construction house there. But with the onset of coronavirus they changed course, choosing a larger, four-bedroom house that could potentially become their primary home, and that was already completed so they could start using it right away. They paid $770,000 for the home in early May, and have been spending weekend there with their 5-year-old son Patterson.
