3) Any specific states you recommend to set up any of these (Not sure where I'll be purchasing property yet, maybe Detroit, maybe Cleavland, maybe Augusta, maybe Des Moines, maybe Saint Cloud, maybe Memphis...)4) I already have a LLC based in Hong Kong (We call them limited companies, but the principle is the same).

@Gary Abrams A cloud based solution would work really well in your scenario of having other family logging in and helping with management. 

They will help you clear any clouds on the title and know whether you can close in "7 days" as offered to the seller.

Including the cloud brokers like REAL and EXP Realty- all the brokerages I've researched so far require to join a local MLS & NAR.

Quote from @Robin Cloud: It's hard to make a decision based on this.

Leverage technology early and put everything in the cloud, so you can access info wherever you are.Make sure to get properly licensed and obtain E&O Insurance.

Since I only have these 2 units for now I was thinking of using one of the free websites (Cozy, Tenant cloud, etc...).

Now there is clear cut law that if wholesaler does not follow the rules they cannot tie up EM or cloud title etc etc..

St Cloud MN Duplex, list/purchase price $259,900market rents $1,610 per unit BUT yes, if one really wanted to sec8 income standards are $1,957 per unit so one could go that direction if wanted be.

In our company we basically use the cloud based expense reporting software that takes care of the accounts, invoicing and billing in a precised and significant manner.
