Duplex purchase- remove tenant

[Nate Valentine]

I am considering purchasing a duplex. Both units are currently occupied and have a month to month lease. The current owner described one tenant as being significantly behind on rent. The other tenant would like to stay but understands the unit has been significantly under priced. How do I make an offer and ask for one tenant to be removed and give the other an opportunity to stay at a higher rent rate prior to closing? Is that possible?
