Rafael,
Unless you are looking on buying a full time job, Why would you buy a 10 unit with out having it managed. I did this for myself but it was my full time job, and even then the Olly time that I was really able to scale was when I was using other professionals.
You say that you are doing well in your logistics business. Keep working on that. Let someone who has already learned the Real Estate business work in that. Most of the investors that have been able to scale have their entire team. Let the pros do their jobs, whether that be Agent, Property Manager, lender or Acquisitions.
You have to keep your long term goals in mind and not just look at the little money that pro's charge. I have found for me a landlord friendly sate like Florida is hard to beat. I moved investments down from the midwest where management was getting challenging. I also believe that the appreciation on a long term is better in an area that people are moving to.
Best of luck and please connect if you need more help.
