I'm only replying to the original post by @Michael L. I didn't read the other responses as not to skew my thoughts.
There are several things here that you didn't give the time to develop. In a vacuum, your post is dead on. You only had one property, which isn't enough to see the power of real estate.
The first point is you forgot about appreciation. Over time that property is going to be worth more.
You also forgot about the power of compounding. In conjunction with appreciation, you eventually have enough to refinance, get your money back and repeat. Buying a second property with the "same money" leads to an infinite return technically.
Also, you forgot about the tax benefits. Based on your numbers, depreciation alone probably made those gains almost tax free.
Imagine this. You buy a property, hold for 5 years, refinance and get your money back. You repeat, except this time, it only takes 3 years. Appreciation + cash flow on 2 properties allows you to buy a third property. Rinse and Repeat except this time it's 2 years, then 18 months, then 12 months, before you know it you can buy a new property every few months with your cash flow alone. Now, you're in a position where you can buy a 12-unit apartment and start the rinse and repeat cycle all over again with those property types.
With stocks, unless you sell, you can't use "cash flow" to buy new stocks, you have to use all seed money (dividends are taxable too). If you sell the stock, you pay taxes, then you can reuse what's left. Real estate lets you use most of what you have with little taxes (thanks to depreciation) or tax-free (thanks to refinancing). 1031 exchanges let you upgrade to larger properties without paying tax as well (in fairness, it's deferred, but indefinitely potentially).
That's why I invest in real estate because I believe it's far superior to stocks (just my opinion). HOWEVER, I believe to truly be successful, you have to be passionate about real estate. What you've done is only looked at the negative of real estate and the positive of the stock market. That's not a jab at you by any means, but just based on your post, it sounds like you're just not passionate about real estate and are more interested in just parking your money somewhere, making a modest return and not having to spend any time on it, and that's fine. There is nothing wrong with that if it makes you happy and it's what you're comfortable with. I think the stock market is the best place for you and again, there is nothing wrong with that.
