ELI5: What are REITs(Real Estate Investment Trust)?
gpt
So lets say that you are an investor, and you would like to purchase a Skyscraper or a Shopping Mall but you either don't have the millions of dollars it would cost to buy one or you don't want to spend the millions of dollars required on just 1 building.

A REIT is where you and other investors can get together and pool your funds to purchase either a single building that you would otherwise not be able to afford or to invest in a range of properties that you would otherwise not be able to afford.

There are 2 other important advantages to REITs:

1) They are liquid - once you buy a shopping mall or even just a single residential investment property they can be very difficult to sell. It can take a long time and cost a whole lot of money. Often REITs are listed on Stock Exchanges so they can be easily bought and sold just like a stock in a company.

2) REITs are professionally managed so you don't have to worry about personally managing the property.
