1. Kids. Kids in private school. Staying home with kids. My career just didn't advance the way it could have if I had kept working during those year. Also medical expenses for kids.
If you're interested in sharing, I'm curious how much the private school has affected your savings/FI timeline. How many kids, how much is tuition, how many years will you pay it (or have you paid it).
2. Buying a house in 2006 and then dh getting transferred two years later right after the housing crash. Ouch.
Ouch is right. :(
We weren't forced to sell after the crash, but we were unlucky enough to put our house on the market in 2007 as prices were just starting to drop -- and foolish enough to buy our new house before selling the old one. So we bought our new house right before the prices crashed (10 years later it's finally just about worth what we paid for it, not accounting for inflation). And our old house sat on the market for a year before it finally sold, at about $100k less than its peak value in 2006. Paying two mortgages for that year really stunk.
I guess our poor/unlucky real estate timing had us paying $100k more on our new house, and netting $100k less on the sale of our old house. So $200k worth of "bad real estate luck" would take 2nd place among things that (negatively) affected our FI date.
I have a good friend from high school. He and his siblings went to a local private school......not boarding, and from what I recall, it wasn't too expensive. However, I was wrong. It is now 14.5k per student. Or 43.5k for three kids....each year. The friend and his siblings all went to a private (middle of the road) college.
He now has 3 kids. Says it's like buying a new lexus each year. What I will never understand is when people choose private when the local public schools are same or higher quality.
From what I can tell, his friends turned out about the same as my friends at the public school. Some did great, some did average, and some poorly.
If your public school sucks, then I understand, but this has to be one of the biggest drags on wealth building. Former neighbors pay 46k per year for two kids. Their middle school not so good, but elementary and HS are fine to good. And, there are cheaper high schools. So, over K-8, they will pay about $200k per kid. I would guess the dad earns around 200k per year, so well off, but not uber rich.
As for me, earning a lot and saving a lot, but dealing with the associated stress allowed us to reach FI earlier than otherwise. Not that I would recommend that route.
