This move makes no sense to me. You spend all that money for a slightly bigger house and you don’t even have kids yet.
Even the fact that you live in North County and don’t have kids makes no sense to me. You are paying a serious premium for shools and not making use of it. Move somewhere that is nice with a crappy school district and save your money. Or, move somewhere mediocre with a crappy school district and save even more money. When you have kids and they get close to kindergarten age, then go for the over-priced neighborhood w/ the great school district and you’ll be ble to afford a better place because you saved up.
