Live-in Property Manager in a 4-plex

[Aman Khan]

I am going to take a look at a 4 plex in the next few days. I found out that the building is partially occupied and one of the units is rented out by a property manager. I'm not sure how exactly this works. I've heard of hiring property management companies that you pay a percentage of the rent but how exactly is a live in property manager compensated. This will be my first property and I'm buying with an FHA loan. So any advice is appreciated.
