Thanks, Happy. I've been very reluctant to change my mindset on the private school, but after removing my emotions and simply looking at the math (which was HARD to do), it just made more financial sense. All of my objections were really unfounded, as the same issues I was concerned about would be present in their current school, just in a different form. So, there you go.
Plus, in the new area since it's so highly coveted, renting out our place after the kids graduate, should we decide to do so, would be pretty easy. The rent vs. buy calculator referenced around here showed that buying would be the better deal after 3 years, which isn't that long. And it's a highly walkable area and closer to the Hubs' job, making it even more attractive.
