@Eli JermanYes, you should hire a tax professional.

(One virtual and one local).   

Consider Hiring a Legal Expert- German property law can be complex.

In my opinion, in many cases it’s better to invest in a property that costs less and is a bit under decorated - then hire a really good decorator to upgrade at least a few rooms for the unique,  “wow” moment in photos.

Working with Real Estate ProfessionalsLocal Real Estate Agent: Choose an agent experienced in student housing.Property Management Services: Consider hiring a property manager if you’re not local.Inspection and Appraisal: Conduct thorough due diligence to avoid costly repairs.6.

I wonder if there is a way to web scrape for when a new realtor is hired or passed exams in the area so that I could hit them up immediately.  

If the partner moves out of state next year they are still a 10% owner, but you simply hire another property manager for that same 8-10%.

That could be your PM company if you plan to hire one. 

Yup, I think if hired someone to do a job, that they have an obligation to do that job to fullest.

It depends on who you're hiring but that seems fairly standard.
