Rehab While a unit is occupied?

[Tony R Fox]

Hey team!

I am in CT and I am looking to do a BRRR and have a duplex in contract. However, how do I do a rehab when a tenant is occupying a space? I can tell they have been there for a while and the wear and tear on the unit show. I want to give them a great living experience. Not looking to to crazy with the rehab but general updates the previous landlord did not do.
