Renovation on occupied unit

[Cory Peters]

I am under contract on an occupied rental. Once we close I don’t want to see evict tenant as they pay on time at market value and have also been there for years. I’m running into and issue, during inspection we found some water damage to a portion of the subfloor and joist under the kitchen sink. Replacing/sistering the joist and fixing the water issue shouldn’t be a problem, however how do I go about the subfloor? Do I wait till the tenant leaves to do the Reno?
