What about if you set up a maintenance company that maintains all of the properties, then you have a real estate attorney prepare all of the lease agreements.

Can you explain how your company solves the partial note issue? 

HELOCs are not available because they are residential loans guaranteed by individuals and what you seek is a type of commercial loan or credit line which are available to seasoned companies with proven financial track record.

Quote from @Mark Forest: The company I have invested with has done a great job explaining why this is happening and what they are doing about it. 

Having a long-term rental while living abroad is do-able.Flipping houses while abroad, in my opinion, more difficult, especially if its your first go around with real estate.I would recommend taking a flight and staying in the area for a week and inspect the neighborhoods and make connections.You can reach out to @Elenis Camargo who has a PM company in Jacksonville.Best of luck though.

There aren’t many residential development companies operating at this level, which reduces competition and risk.

Of course, I run a cost segregation company BUT I would recommend that regardless.

With that being said, in a worst case scenario, you can always hire a property management company to handle the day to day items if it comes to that. 

you are going up against people and companies that spend thousands or even tens of thousands of dollars a month in marketing. 

A few that sell and manage, or know management companies.
