And real estate is not that bad an investment in general, if you do not rely on it going up forever. The real problem is its illiquidity.
All investments have up and down. Just because there's an overdue big downturn in real estate, it doesn't mean it isn't a viable investment vehicle. Actually your negative reaction to real estate represents the general public sentiment, which is a perfect contrarian indicator. It really points to now it's the time to look into it to invest.
OP is 25 and has just seen the big housing downturn, which is great for him, lessons learned on other people's expenses. He has the next couple years to learn about it and accumulate capital to get into the game. If he asked couple years ago, I would have advised against it.
