The "positive" about investing in shares is that there is no pressure to invest more in the same shares/firm.
Property - Say one buys a plot. It produces little/zero income but requires some cash outflow. We can either wait for capital gains or develop it.
Wait for Capital Gains? Pay for a wall, askari, rates, etc.
Develop it? Time, money, contracts, contractors, county government, etc [Not everyone is cut out for this. Not me anyway]
Except for a Rights Issue, shares don't require reinvestment.Plus you can choose not to buy into a Rights Issue. If you buy 100 shares in a firm, there's nothing else you need to do. Investing in shares/bonds need not be a full time job.
A typical rental property requires some maintenance. If one has a large enough portfolio, it can become a full time job. Some enjoy this sort of thing.
Of course, one can buy duds in both cases.
Shares in ARM, NBV, KQ, Mumias, etc
Land - despite due diligence - on a road reserve or riparian land. Or simply a fake title. Or one that is disputed. It happens.
Property (developed) - If bought from the other MM. Poor jamaa - on some other thread - who got stuck with a piece of crap bought from iTrade.
MOST IMPORTANT to me - Peace of Mind. The rest (money, returns) is irrelevant if I can't have peace of mind.
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
