I hope you and your family are doing well and staying safe.

Networking, local meetups, door knocking, mailers, wholesalers, online forums specific to your area of interest.  

There are landlords who are proud to own properties while offering their communities a nice and safe place to live (and enjoying the benefits of having someone else pay for your appreciating asset).

The "Initial Filing" is extremely important to get this right the 1st time as there are limited safe harbors for mistakes to avoid the penalties.

Quote from @Zach Howard: Quote from @Jonathan Greene: If you are looking at properties in the US only on Zillow, and not seeing them in person (I know you are in Hong Kong), this is just an effort in futility because you can't underwrite single-family or small multifamily deals only online.

It will be easy for you to check if they paid on time, as you can check instantly online.  

Quote from @Michael Smythe: @Tuan Tran don't fall for all the hype about S8 by so called online "gurus"!

I also recommend a bank that has local branch that you can go into vs having it 100% online.

Since my son knew how to do it safely with ropes and harnesses he made like $3,000 in 2 days! 

Unfortunately, while all the online places area great sources of information, you are much less likely to take action, or find someone to shadow, when online in a forum.
