Onsite manager eviction upon close of escrow.

[A Bee]

Hello BiggerPockets members!  Thanks for reading this post, very much appreciated.  If you're able to give advice on this subject, thank you!  So I am in escrow on an 18 unit apartment building in the City of Los Angeles.  The building is rent controlled (RSO).  The on site manager, who I met and am not so fond of continuing with, occupies a 2 bedroom/1 Bath unit and according to him, does not pay rent in exchange for his onsite management "services".  The apartment building was not managed that good and there is no contract between the onsite manager and the current owner.  Since the building is 18 units, I would be required to put an onsite manager at the property.  I would prefer have the onsite manager vacate, and then I would rent out that 2 Bedroom/1 Bath at market rents and then move a new onsite manager into a currently vacant studio and ask them to pay 2/3 of market rent and I would pay them an hourly wage for whatever work they do at the property.

So... any way /advice as to how to have him vacate his unit?  Since there is no contract, does he have any rights or is it possible to terminate his employment whenever?  Also, he has no rental agreement either, any further suggestions on how to have him fill out his estoppel in order to be able to vacate his unit?

Thank you very much for reading this.  Last time I asked a questions you guys were awesome, thanks again.
