When to prefer readwrite properties? [closed]

I've often heard that readonly properties should be preferred but when do we prefer using readwrite properties. Generally, is it better to create a new viewModel with the new property changed or modify the property?
More concretely, let's say I have a selection view. When I tap on the view I update the viewModel. One way I could do this is to create a new viewModel with all readonly properties and the only property that differs is the isSelected property. Another option would be to modify the isSelected property directly. Why should I prefer one over the other?
