Hire a loan servicer - plenty of discussion and recommendation on BP on this topic and some recommendations for servicing companies 

I am doing owner builder so hiring subs for each job.

Consider managing remotely you'll have to be willing to travel 3 hours when needed or find a way to handle it virtually.

Hi,I am thinking to hire one duplex with two property managers for each unit (as existing property manager taking too long to find good tenant).

Hire an interior designer.💡 How do you keep rehab costs under control and avoid surprise expenses?

You should be able to open an account virtually with them.

It is important that you hire professionals who have experience working with foreign investors.

edit to add: I just saw their page says they're also hiring for admin assistant, transaction coordinator, and wholesale acquisition trainee - wonder if those would still get me good experience and lessons without all the fees

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

You could arrange to have your cleaners accept the deliveries at the property or hire a local handyman to do same and even assemble furniture.
