What should I invest my money to retire early?

The first two answers mention real estate but the most important part of real estate investing is "positive cash flow". Make sure the rent more than covers the mortgage + property tax + maintenance. If you don't have positive cash flow and are just counting on price appreciation, you are gambling, not investing.

You haven't specified how many years you have until retirement or what rate of return you need to retire early. The mix of stocks, bonds, real estate or other investments depends on your time frame, risk tolerance, how much you have to begin with, and how much you will need in retirement. Without this information, how can you expect a meaningful answer?

real estate

you can even hire a property manager if you don't want any late night calls.

If you put 20% down you can avoid PMI and have a positive cash flow and still have someone else do the dirty work of paying off your house.

I bought my first house just over 3 years ago, they have gone up in value so much I have started refinancing. Someday I will retire early as I keep buying more houses. In as little as 15 years after I started doing it.

Food, Sewage, Funeral Homes..........

Every one has to eat, **** and die

depends how much are u talking about? Lower amounts dont matter as much as larger amounts especially if you are young early to mid twentys

You are asking a loaded question. In the next ten years there will be 76,000,000 people retiring, that alone will shift much of life as we know it. Real estate may peter out as baby boomers sell their big homes for smaller ones. Stocks may not do so well with less workers to perform tasks. Commerce (GNP) will slow as there are less buying dollars. Foreign powers will gain strength, economic and political.

Sirius radio, it will grow by double every year for the next ten years.
