REIT vs Multi unit investing

[David Ma]

My question for all of you guys is that while some of you guys are investing in multi units that provide a rent income of 10-15% return. My question is why not invest all this money to Real estate investment trusts? Most of them provide the same amount of returns if not more. Why waste the time of going through all the hassle of it while you can just get a more passive income? Is it insecurities of not having something physical ?
