Investing passively (none accredited/ sophisticated investor)

[Ahmed Al-Absi]

Good morning everyone, 

For someone who'd like to capitalize on investing passively in multifamily businesses, where and how can he/she look for to invest in a smaller amount. Obviously for an operator to create a, for example, 506 B fund, they're not going to be able to advertise the investment per SEC regulation. So questions that come in mind, where to find a good operators and how to vent them to make sure your money doesn't end up in a scam?

Your thoughts are appreciated :)
