I didn't know anything about life insurance, which hasn't been a problem since I don't need any just now. I also realized that my auto and renters insurance deductables were too low, and I had coverage I didn't need. This covers the trade-offs between buying and renting, between selling a house you're moving out of and keeping it while renting it out, and explains the different kinds of home loans. The book explains the terms and what to look for. Car loans are bad, home loans are okay, no loans are best.
Cars depreciate, homes appreciate, and home loan interest is tax-deductable.
Besides, you're not doing your kids any favors if you have to leech off of them later in life. Invest your own money. Buy some darts, you'll probably do better. In retrospect, this is obvious, but I hadn't really thought about it. If the market goes down, you won't be able to buy the house.
