You said your "leveraged annual return" will be ~9%. This is incorrect. Your cash on cash return would be about 9% with the example you gave.
Your "Internal Rate of Return", or IRR, will likely be somewhat higher than that, depending on several assumptions, esp. regarding the sale of the property and capital expenditures, but I would bet it would pencil out to 15% or so based on the example you gave. IRR includes non-cash items such as principal pay down, tax advantages, etc.
I won't try to convince you that turn-key, class A or B properties will offer significantly greater returns than the stock market. They won't. The barriers to entry for turn-key properties are low enough that anyone that can get a mortgage can do it. If everyone is capable of participating in a certain investment, then the returns will normalize.
So why do people still buy real estate vs. the stock market?
1.) They might consider it less risky than the stock market.
2.) They might want to take advantage of the tax treatment of real estate (passive income losses, depreciation).
3.) They might want to hedge against inflation by owning something tangible.
4.) A host of other reasons, usually peculiar to real estate.
How can you do better than the stock market?
Dig, dig, and then dig some more. Learn about real estate by engaging in it. Study it. Observe what others are doing, befriend them, and learn from them. Minimize your mistakes and protect your principal.
Then apply your time, network and superior knowledge to participate in investments that are inaccessible to the general public and you will (hopefully) generate outsized returns.
