Navydoc, one thing you might not have considered is that landscaping and maintaining a large lot in San Diego is very expensive … especially relative to what you are used to on the east coast.
I am not familiar with Stonebridge but if you are going that far inland you might want to consider getting a newer house in north Poway that has a finished landscape. There are some pretty good deals up there these days and most of them do not have Mello Roos.
