That is online with what we’ve been paying when we were able to find help.

you can find all the info online"...it's like, no sh*t you can...all the information ever is online!

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

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.  

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

I’d love to hear about the crime rates or any other issues (which we cannot guess from the online stats), and how easy or hard it is to find reliable tenants and property management companies.

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. 

Propelio is especially popular in Texas, so if you're investing in areas like Dallas, Fort Worth, Plano, or Frisco, it’s worth exploring.Public Property Records: County appraisal districts (CADs) often have free online tools to search properties by owner name or address.

Since the last time I was online, I have grown the investing to fix and flipping and a portfolio of 4 properties that are producing passive income.
