I have done stocks but never property. However, it seems to me property investors don't seem to spend as much time on active investment compared to stock investors. Stock investors spend more time monitoring the market. So, is property investing more passive than stock investing? Passive means less time is needed.
For a person who wants to release more time to do other things besides investing to grow his money, would real estate be a good alternative?
Either one (stocks vs property) can be nearly completely passive or extremely intensive. It's entirely up to you. If you want to directly own rental property, I can almost guarantee this will end up consuming more of your time and energy than you expect at least initially.
