REITs are usually simpler. Rental properties are usually more hands-on and more operationally demanding.
Why REITs appeal to beginners
REITs let you buy real-estate exposure through the market without managing tenants, repairs, insurance claims, or vacancies yourself.
Why rentals still attract people
Direct property ownership offers more control, possible leverage, and a very different risk/reward profile. But it is closer to running a business than owning a passive fund.
Bottom line
If you want simplicity and liquidity, REITs are often the better beginner path. If you want control and accept the operational load, direct property may be worth deeper study.
