Really appreciate sharing your experience with us Paris and NYC to OC! That's very helpful.
Looking back we've always lived in older/smaller houses located in a very good school district even before we had kids, hoping that the houses will hold values more. They did, I have to admit that, especially during the housing bubble period, but after all these years, living in a new house is definitely very attractive to us.
For two kids 2 years apart, not same gender, at that ages you think they would want their own bathrooms? Now they happily share one and don't even want to go to different ones.
