Creative ways to ask tenants to move out to rehab apartment

[Dustin Murphy]

I just closed on my first deal that is a 3 unit building. I want to ask two of the tenants to move out so we can rehab two of the apartments and raise rents. The current rents are below market value but the units could use a little freshening up to justify the rent increase. Does anyone have any suggestions on ways to ask them to look for a new place? If it comes down to it I may offer cash for keys but looking for other options before I go that route. Thanks for any advice in advance.
