I urge you to ask this question at quora. http://www.quora.com
People there give thought out multiparagraph answers.
Just some things that come to mind. In some places at the US real estate gains value at greater than 7% annually. The many-year average return of the stock market is near 7% So if you invest in real estate where it grows faster than 7% you should be able to equal stocks. The thing is that you can look at things like "best places to live in america" https://search.yahoo.com/yhs/search?hspa...
and find the places with the best schools, for you that likely means the best students! So if you can find a "best" city with great schools and appreciating real estate you could improve your life two ways at a time!
Ask at quora though.
