I do construction management for investors and I usually find them good contractors at good prices. 

@Steven Wetherillwhat about property management?

And even far less succeed with a multifamily real estate portfolio.

The place where you can add value with no money is a situation like: you find project A, it is a 120k purchase and it should need 80k rehab but you can get rehab done for 65k cause you can do some of the work and you know how to save on materials and you can manage the rehab. 

I have a mobile home park in Idaho which will have an onsite property manager.

What does it look like to scale a portfolio in Europe?  

These are 2-bedroom, 1-bathroom properties that I had originally planned to keep in my rental portfolio, but my plans changed.

I manage quite a few properties in those markets.

Don't change jobs or income yet.Once you do and you think you can manage the payments based on your new income, maybe once you get the rooms rented.Then if you want to switch there are plenty of opportunities. 

Don’t have the time to do property management right now however as I have a full time W2 (accredited investor) and a family to raise.
