Over time, some people's mindsets (or their needs) regarding homes change. Snowbirds & snowflakes might purchase a home in TV as their second/vacation home. If they were to become frogs at some future point, they might opt for a different style/type of home altogether. Some folks like new homes and will move on to another new home every now and then. Others might choose to downsize (or upsize!) once they've been living in TV for a few years.
Different strokes........
