I'd start by giving all residents the required notice (usually 24 hours) and go inspect the units as quickly as you can. 

I started investing real estate in 2022, and own a couple of doors in South Jersey.

You should have already started the eviction process!

I want to start investing in real estate in America in the near future, since I am not in America, I live in Europe, more precisely in Serbia, any advice and contact will mean a lot to me.

From there you can start to identify what you are looking for.Where do you land on the follow spectrums:Cash flow and AppreciationLong term or Short term needs (waiting for growth vs get out of my W2 now)Long term rentals, Mid term rentals, Short term rentalsBuying close to home or coast to coastSelf manage or hire a PMIf you can narrow in on those, you essentially have your buy box. 

I strongly recommend a multifamily to start out when using a DSCR loan.

As I start down one path, I have more questions which leads me down other paths with even more questions.
