We have discussed funds and the like, but remember, the guy has to live off the money as well. What good is 10% annually if you are not really keeping it because you spend it to live.
deterass said real estate, I went along those lines as well. Like 20K down on 5 different properties in an interest only loan. Hold for 4 years and flip. Somewhat risky, but then again this is South Florida and it can easily be done.
Perhaps a split of 250k/250k with one half going to real estate, the second half in a fund that is just going to grow and double in 10 years.
