It can be said that many millionaires understand that property or real estate is a low risk investment but has a high profit potential, they understand that the increase in population will require a house or apartment so that it becomes a good business opportunity.
When they choose a real estate investment, of course they already understand in detail about the investment, both the losses and the benefits. You are right, with the current population increase, of course they will need houses for their homes and it would be great if we had a property business, of course it would be very profitable. and it's better if the property business is close to urban locations, of course it will be even more attractive.
There are many aspects that support relatively fast price increases such as location and surrounding developments, indeed the property or real estate business does not have a big risk, but you must also realize that the profits in this business take a very long time, indeed it is still quite worth it for the future but we also have to have calculations for business opportunities or other investments to get bigger profits.
I think the property or real estate business is suitable for people who already have more money / more money after doing business or other investments.
