Took possession of three unit apartment today. Top Priorities?

[Carini Rochester]

I just left my closing and now I own an occupied three unit apartment building. The building is in good repair. I have only met one of the tenants. I plan on self managing. What are some of the most important first steps I should take? What should I communicate to the tenants? How should I communicate? What should be my top priorities? I appreciate any suggestions and advice.
