purchasing duplex via fha/asking tenants to leave

[Zach Barnard]

Hello there! Long time listener of bigger pockets, new to the forum. I’ll preface with; my fiancé and I just signed a purchase agreement to a duplex that I believe to be a perfect starter situation to our real estate investment career. We are buying with an fha loan and both sides are currently occupied. We don’t yet have the old rental contract between the tenants and seller but we are curious: how do we go about asking the tenants on the one side to leave? From what I understand, we have 90 days to occupy the residence and would prefer our first transition to happen smoothly. Is the old rental agreement between seller/renters null and void once the deal closes? Thanks!
