I would agree with the majority of the posts. My first word of advice would be to wait. I do think you could do better waiting but I understand why you are buying now.
If you are not going to wait then go with the home that will provide more harmony for your family. Both are great school districts so you cannot go wrong with that pick. Also agreed with the point about more lots available in 4s then Portico. For the record I think there may be more defaults in 4s then in CV but it is just an opinion so take it with a grain of salt.
I think trying to speculate on which home will appreciate more is pretty tough. I am sure if someone were motivated enough they could give you appreciation numbers for each area for the past few years. I am kind of tired so sorry about that.
Anyways, go for the harmony, the better deal for the money, measure which has higher Mello Roos etc, what is better for your commute, etc…
